Altcoin's in general will always be able to circumvent the governments, but when he mentions only like 3 companies in the world are capable of producing the hardware to mine, and are going to want on/off switches
It is not end game for crypto but a very sizable constricting point.
The value of alt coins likely won't ever match that of the potential of bitcoin, but if bitcoin is forced into a centralized model, that's it for bitcoin.
The unlimited resources of the government, and the very purpose of government, will absolutely attack whatever threatens it, if bitcoin is a threat, it will be attacked, changed, molded. Do not think even if the .gov fails, they won't go down without a raging fight.
