How much crypto is traded to avoid corrupt regimes and hyperinflation? 1%? 0.1%? There's probably a few zeroes in there.
Regarding Netflix, it's better for the environment than buying a blu-ray and blu-ray player or driving to the cinema. Can the same be said about crypto?
You can't know, and that's the point.
You can leave a country carrying nothing but a seed phrase in your brain and with it all your wealth, if you need to. Just the fact that governments know that this can happen can change things.
If you have a pile of Fakeistan dollarydoos you wish to convert into USD, spending those dollarydoos in Fakeistan on electricity to apparate some Bitcoin, then converting those Bitcoin into USD in the USA does not create a foreign claim on Fakeistani economic output. On the other hand, directly exchanging your dollarydoos with foreigners for USD does leave those foreigners holding a pile of dollarydoos, which does represent a claim on future Fakeistani economic output.
How has Bitcoin saved Venezuela? Well it helped a small number of people in the country, sure. It obviously didn't fundamentally make any difference, and it's not going to anywhere else either. For the average person Bitcoin is not easier to acquire, use or manage than USD in locations such as Lebanon, Turkey or Venezuela.
It certainly is in terms of being only for entertainment and no deeper use. However the amount of energy wasted here (let’s say 300W on a fairly high end machine) falls into the average area of energy spending per person, and thinks like driving or keeping unnecessary light bulbs on is same or worse. Crypto things however seem a whole other level of energy waste.
According to the New York Times, Bitcoin uses a little less than half a percent of all the electricity consumed in the world [1].
