Financial security isn't worth anything in face of extinction. Bitcoin inherently works against human prosperity. No matter the riches we achieve, PoW will take a massive cut.
Please, play it through in your head: What would happen to the PoW system, if we achieve almost infinite energy proliferation? E.g. some scifi space solar energy harvesting. Don't you see how Bitcoin works against our future?
You need to chill if you think the demand is high enough to literally wipe out humanity.
And keep in mind, capitalism (when working properly) is supposed to find minima. Not create further barriers to getting things done. The group that gets the job done at the highest output:input ratio for as long as the problem they are solving is relevant was the intended optimization point. Irrational markets being what they are, this frequently does not converge as planned.
Without regulation, most essential markets fail humans.
And finally an ancap "free market economy" was the default state of the world and the whole of human history has been the struggle to overcome/refine that stake based hell.
Yeah, I think that's an extremely ignorant and outdated ideology. Which is evidently progressing towards human extinction.
Optimizing towards the metric of monetary reward/economic growth is just horribly disconnected from human welfare.
There is also the fallacy of assuming all things interchangeable for market dynamics when in reality some things running out means "down-regulating demand" by killing off most of the population, e.g. phosphate rock.
Capitalism isn't set up to get us two cookies later. There is just no incentive for the market to give a fuck about humans. It's like the "stamp making AI" thought experiment. Or the attention optimizing algorithms mindlessly destroying political culture. Oversimplified metrics spiralling out of control.
Tho, economists have realized this and most markets are recognized to fail without regulation for their inherent nature. E.g. housing, water, electricity, education, ...
