Second, natural gas is a finite resource and the vast reserves are vast… for now.
What north america also has are vast tracts of land. The ideal place for nuclear reactors since large bodies of water are often close by. Same argument for wind turbines.
The difference when you have your own supply is that the price becomes a policy choice. The government can easily decide to prioritize the domestic market and limit exports.
They can, and have done this in the past, e.g. the US ban on export of crude oil.
But this does not change the point materially. Not exporting and consuming gas domestically at lower prices incurs an opportunity cost as the same gas could have been sold for more aboard. So net-net the people will pay for such a policy choice.
I don't think it's so simple. Cheap energy can make entire industrial sectors viable that otherwise wouldn't be. You could easily end up ahead by putting that energy into production of goods that are higher up on the value chain rather than exporting it directly.
There will be higher order effects, there always are. I don't think the second order you brought up above changes the argument either. If investing in a certain industrial sector is desirable, then why not sell gas at the international market price, and use the extra proceeds to do the investment at the level that makes sense. That way you can at least tune the investment to a level that makes sense, rather than having it depend on the delta between the local and global market price which will depend on a ton of other factors.
Note that I'm not saying that's always bad to protect a local market. The assertion was that North America has enough gas causing it to be isolated from the global market pricing, and I'm still very skeptical about that claim.
It is traded internationally, but oceanic shipping of natural gas is expensive, and capacity is limited (export ports, import ports, vessels), so the domestic market doesn't see the full effect of international pricing either.
I wish we would move from gas to nuclear since gas has a major climate impact, but low US gas prices do make that more difficult.
The US also happens to be especially well situated for solar and wind, making life even harder for nuclear. That comes with some bad news too, because we don't really have great storage solutions yet and we're terrible at building long-distance transmission.

Well, duh. Of course it's less expensive if you only have to care about the lifecycle of half of your process.
Gas still leads coal and is cleaner burning so less polluting in othet ways but its not quite the GHG slam dunk it is if you just compare CO2 from combustion.
Renewables and nuclear are way ahead of both.
However, leakage in both new and existing gas wells, plus leakage all across the gas distribution infrastructure make this worse.
However you are right, and its kind of funny. The US despite not signing the Kyoto protocol actually achieved those goals because of gas while most other nations failed. France of course was already green by the time the conference happened.
I don't think anybody knows which of the fossil fuels leaks more methane. They all leak lots of it, but the people with access to measure the leaks won't.
Or ever. Breeder reactors aren't a new idea. The concept has been around half a century, and they were put in commercial use 35 years ago. Thus far with enormous cost overruns and spectacularly bad uptime.
It's good that we research these things, but we shouldn't base our energy infrastructure on things which aren't commercially available for good reasons.
It's sad for everyone that energy infrastructure turned out to be a really, really hard problem, but wishful thinking doesn't make it go away.
We have several decades of empirical data to suggest this. A regime that has other basis of considerations can of course do what they want.
https://en.wikipedia.org/wiki/BN-1200_reactor
In 2015, after several minor delays, problems at the recently completed BN-800 indicated a redesign was needed. Construction of the BN-1200 was put on "indefinite hold", and Rosenergoatom stated that no decision to continue would be made before 2019. In January 2022, Rosatom announced that a pilot BN-1200M would be built by 2035.
The BN-800 reactor connected to the grid in 2015. That's a gap of 20 years between building more BN-series reactors.
Meanwhile Russia has completed 6 conventional pressurized water reactors in the last 5 years:

I think it's fair to say that breeders are still too expensive and complicated to compete with conventional reactors. The money saved on fuel is just not enough to justify the extra complications considering how inexpensive uranium remains.
I frankly think that these considerations are exaggerated in countries which already have nuclear bombs (like USA, Russia, China, France, UK, India, Pakistan, Israel,..). Japan does not have a nuclear arsenal, but, frankly, a normal nuclear power plant can also produce plutonium, maybe only somehow more visibly, so Japan might have built nuclear warheads on a year or so, had they decided to do so (and violate their Constitution).
But sure lets kill a great program to build next generation reactors and solve the 'nuclear waste' 'problem' by preventing that.
Just another one of the many ways the public opposition to nuclear has prevented all the progress.
Japan has to import liquefied natural gas at great expense so the economics look different to them. The "plutonium economy" where fast reactors are used to breed fuel from the common ²³⁸U is particularly appealing to them because they have at least a century worth of fuel mined and above ground, some of which is labeled as "nuclear waste". Such a system uses uranium so efficiently it seems it could be made sustainable by extracting uranium from seawater.
The last round of interest in fast reactors was mainly about fuel economy and people believed then that fast reactors would have a higher capital cost, but the next generation of nuclear plants has to be economically competitive and that's not going to happen so long as the powerset is a steam turbine so the main appeal of alternative reactor types today is getting rid of the water so you can run at higher temperatures with a dramatically smaller and potentially cheaper gas turbine powerset.
Such "5ᵗʰ generation" reactors are still under development and won't be making a contribution to the grid for a decade, but clean energy is a marathon and not a sprint.
