Do you expect people to wait by while billionaires pour trillions of dollars into replacing them? Evidence takes years to mount; present events are moving far faster than that. Your argument is the exact same as that of COVID denialists in 2019 -- that we don't know how bad it'll be yet, that there's so little evidence, that we shouldn't jump to hasty action before getting results in. Empiricism can only go so far.
If I knew someone was spending hundreds of thousands of dollars building a big laser pointed at my house, I would not wait for "quantified evidence" of its effect to take some sort of action. The only real debate is what kind of action.
> also, if the worst case scenario does happen and most of the population finds itself without money. there are other ways to live with very little money.
If you have so little attachment to your money, why hold on to it at all? Do not be upset that other people are operating on a slightly larger time horizon than you are, and are interested in their livelihood not just today, but three or five years from now.
