But yeah, if we want to break worldwide barriers without ceding a sovereign country's ability to control their monetary supply and giving an international centralized body inordinate amounts of geopolitical capital, we can simply use Bitcoin alongside fiat. Bitcoin is the new world currency.
Yup. I don't see why people keep focusing on Bitcoin to replace everything while banks, governments, fiat and Bitcoin can perfectly function alongside each other. We can use the best of all options offered. That's freedom.
Not everyone is interested in Bitcoin to dominate everything. If Bitcoin was to replace everything as some speculative noobs want it to do, all others would practically be forced to go with something they don't like.
Bitcoin can't handle the weight of the whole world, and for that reason we should be happy to have other options helping Bitcoin to evenly distribute the weight of the world population. Bitcoin even with LN isn't going to do it alone.
