I would recommend you read Robert Higgs’ great book, Crisis and Leviathan. Higgs is an economic historian and his book shows how authoritarianism gets ratcheted up one nudge at a time, using historical events as evidence. His book is a great addendum to Hayek’s masterpiece, The Road to Serfdom. If you read those books, and if you are a capitalist as you claim, you would realize small nudges from the police power of the state are policies counter to what you advocate.
It is very hard to take the “sky is falling” predictions seriously since they have almost universally not panned out. Even if there is man made climate change - and that is very much up for debate, there most certainly is not scientific consensus - it is unlikely that humans need to panic and willingly submit our liberty to governmental experts. The Covid events of 2020 ought to be all you need to know to understand government experts rarely are. If we let the marketplace sort things out the problem would be handled much more reliably than giving a group of government bureaucrats authority to resolve things by fiat.
