In short, it would seem that governments are trying eliminate the very thing that Bitcoin--and blockchain generally--was originally designed to accomplish.
Bitcoin's original goal was being p2p digital cash. Nothing that the governments did in the past changed that. Some mixers got closed? That only means they were the weak link because they were centralized. This means that privacy enthusiasts will focus on developing decentralized anonymization.
And blockchains goal was always making the devs rich by selling pre-mined coins. So far governments are not going after this investment scam scheme.
Yes, and the reason you need p2p cash--for p2p anything, for that matter--is to evade government subpoenas. If you don't need that, centralized architectures are far more efficient, secure and convenient.
Bitcoin's original purpose was to create a method of transacting that could not be traced by governments, and could not be stopped by them.
Developers also may be visited by the authorities to see whether they can tag wallet addresses. and this is how blockchains of some coins may not survive. if it's what OP means? if they could do this to mixers why not to the developers? they could just find faults in these developers and if they are resistant, they could just jail them.
No, what I meant was that governments are getting good at cracking down on "absolutely anonymous" transactions that the government cannot trace. It's clear
that kind of "privacy" (as opposed to privacy from criminals and marketers and other citizens) is going to be much harder to obtain, and will probably be reduced to very small networks and very obscure coins--which will necessarily be very risky since they will be such so small. This could effectively kill the entire ability of people to transact in a way that cannot be traced.
But yet the only reason to use blockchain in the first place is to create these kinds of transactions. So why use it?
