I'm not a professional, though. I may need a table saw for some projects, but the projects I undertake that require a table saw are few and are far between. My use won't wear out the saw in my lifetime.
Usage of a table saw in my own shop will be at least a couple of orders of magnitude less -- averaging perhaps a few hours per year. Furthermore, without an angry boss-man looming over me to maximize production, I can spend as much time as is necessary to optimize every operation in a safety-first fashion.
If we assume that it is just two orders of magnitude of difference, then: Spending an extra $700 for a sawstop-equipped saw is rather unlikely to ever pay for itself in my shop at home.
(Now, that's not to say that I wouldn't want this kind of safety feature in my own shop. The idea of losing even part of a finger forever is much scarier to me than spending an extra $700 one time: After all, I can make more money but I can't grow new fingers. It's just not such a financially-obvious choice as it is for professionally-used saws.)
But I remember in that thread a few had said that as part of this, SawStop will be forced to license their patent to competitors.
Maybe that'll drive up the cost of table saws, but to be honest, people like me (at best, a wannabe weekend woodworker, not a pro) have stayed away from Table saws because of a concern for safety, but things like Sawstop being more ubiquitous might result in people like me buying them, and expanding the market, possibly bringing prices down.
Sure, Sawstop does nothing to prevent the big issue with table saws (kickback) but still, having a riving knife + sawstop probably makes a huge difference in the overall safety of using a table saw, and that seems worth it.
No one can start a new plumbing/HVAC small business. Your only option is to go work for Walmart (metaphorically speaking).
This isn't true at all, I know several people who have done it.
I wonder how it is in various states, but at least where I live the actual plumbers get licensed, not the plumbing company. So what can they do to stop it? NDAs? Non-Competes? The state also takes a dim view on such things until you are paying someone a significant amount of W-2 money.
SEO? Brand recognition?
Well anyway, a few months ago I shared a table at a restaurant with someone that worked at a family office, and was buying up landscaping companies. I asked some questions in a polite and friendly manner; nothing too pointed or invasive. But came away with the idea that there is a lot of money out there looking for something to do, and not a lot of good ideas.
Which then leads to plumbing shops were the licensed plumber doesn't even work there and just rents out the license to the business so it can operate. Plumbing certs are a complete pyramid scheme.
So in 5 years or so, we suddenly see laws everywhere that require expensive certifications, new kinds of insurances, audit requirements, and so on in the name of “safety” no one can start a new small business in those industries without a team of consultants, lawyers, big auditing firms, and so forth.
How naive. PE does not enter a market in order to make existing workers into millionaires, but to create a monopoly/monopsony where they can gouge both customers and employees, to extract maximum profit. Quite often, the goal is not even to run the market sustainably, but just to produce optical profits for a quick resale.
A few local contractors may get bought out and become millionaires, but everyone else will be impoverished.
We can probably even predict some next steps. They will recommend and lobby for various 'safety' regulations or certifications that would be difficult for smaller shops to meet, and then pressure commercial landlords, housing associations, etc to require those certifications.
