Nobody expects governments to simply give up. But for a country to have to go full China to be able to prevent the use of Bitcoin is still quite an effort. And even if that happens, you can memoize your master key and try to escape into another country. Much easier than if you have to transport several pounds of gold. So it isn't perfect yet, but still a lot better than any other approach. The argument "but it is against the law" (like money laundering) isn't really a good argument against an attempt to hedge against unfair governmental interventions.
