The mechanisms are used in many countries, Japan tried to and the didn’t succeed mostly because of the ever expanding nature of economics, once you lose population growth, you miss out on the cycle of more customers, more businesses. Kinda like US suburban sprawl, which is in fact too expensive if it can’t keep on continuing, but then transport becomes an issue, not everything can expand continuously, people need to innovate, and we need as many people as possible in the hopes that one special guy thinks up a clever solution.
That reminds me of the series " Can’t Pay? We’ll Take It Away"

It is a complicated thing. That aside you did mention BTC just follows code. Sometimes you say it will not change yet things do get added. No one except of few people really know what BTC is, others just see ‘crypto’ as a whole a good way to scam people that need to invest in something.
The people who generally are in the news promoting BTC are people under SEC investigation or with track records of fraud. But they are very slick talkers. And that’s a big issue for the adoption of crypto because they know how people feel. They can understand how people fear recession , and sugarcoat their advise, showing many statistics (just like you and me do but at least we aren’t driven by pure evil.) and trying to fool people into giving their money voluntarily.
The clear difference between a MLM and a pyramid scheme. Income would be based mostly on how many people you recruit, not how much product you sell. So in a pyramid scheme people will focus on getting people in, no matter how much they invest because the more people get in, the more BTC has value, which will be sold by the early adopters. It’s a very new thing here where people will actually work through while it’s a clear loss. At that point, generally the victims of the scam cut their losses and go to the police but by then the scammers have also given up and left the country because they think governments (except those who do not extradite) are evil and want to put them in jail for no apparent reason.
In general, most use of BTC isn’t things people would do. Like you wouldn’t download a car but i’m sure if it’s possible some people would. I do know people who downloaded and 3D printed different guns to see if it works, and it did with varying results. But 3D printed guns won’t be mainstream even though there is an opportunity in the US, where ammunition is getting scarce so … but still. 
Will the financial crisis and current wars hurt us? Probably, and a lot. Will our economical union still be there afterwards, I think so. For me, I don’t really see BTC as a solution, but I guess if you like to use it so you can pseudonymous transfer certain amounts of money internationally, why not. But it’s for a very small select group of people.
Implementations of BTC and lightning network look like a nice idea but as far as I can see, there is no real use for it and those who really would benefit from it don’t use BTC (or crypto) as currency and thus need to convert in (with loss), pay transaction fees, convert out (with loss) so unless you transfer at the right time of day (at the moment because people that see patters will sell it as a solution and then it will stop being profitable) and the recipient does the same, it’s probably easier and safer to use a bank transfer or even something like Western Union money transfer.
