It may be worth less, but it won't be worthless. I have a hard time seeing another fuel source for long distance aviation (although we may move to synthesized fuel in the future).

Companies will also need feedstock for plastics - that use won't be affected by carbon caps at all.

Those tariffs are also a joke in and of itself. As we can already from the oil price cap idea you can only enforce things when the world plays along, but looks increasingly like the global south is fed up by these dictates. So good luck enforcing carbon caps and tariffs when the majority of the world population doesn't play along.

You can still have them, but ultimately it's the people in western societies that will pay the price with their own pensions and social services gradually degrading.

2nd and 3rd world countries are going to bathe in cheap oil when/if the 1st world bans it.

How do you plan on enforcing the bans globally?

We kinda enforce "don't trade slaves" globally... And "No child labour"... And "don't steal other countries ships when they sail near your country".

"Don't emit more than your fair share of carbon" is just another rule like the others. If most countries agree, but there are a few dissenters, we can deal with it like other international disagreements - warnings, then sanctions, then war.

Currently, we're far from that, because we don't have a majority of countries agreeing on carbon caps.

So the British Navy is gone blockade Africa so they cant import oil from the middle east? Great plan.

Nah - it'll go down like Venezuela [1]. The government of a country flagrantly ignores the internationally agreed carbon caps, and so some country or group of countries get together and sponsor a coup.

It happened to Venezuela because they refused to align with US interests, and with other economic and political issues, they were an easy target. The wikipedia page [1] has a nice summary of the list of countries on each side of the dispute, and you can see a nice 'pro USA' and 'anti USA' divide.

Sponsoring foreign queue is not actually that easy.
