Huh? So coinbase bans everyone and goes bankrupt. Makes no sense. Nor does it make sense to imply that being banned by coinbase somehow locks you out of the blockchain or from using bitcoin directly. You have imported the fiat/central bank mindset into bitcoin in a way that is completely anachronistic.
Haha so he answered the question... it's a valid argument - with government control and regulation (much like Net Neutrality), it can kill Bitcoin. No need to get upset at his argument... because as we currently stand, we are poised and in position to move in this direction.
