Hey, don't forget all the child porn sales and tax evasion! It would be socially irresponsible of us to oppose a new technology with so many wonderful use-cases.

It surely ISN'T proof-of-work blockchain crypto-currencies as currently implemented.

I suppose that there is really very little pressure upon current crypto-currency implementations to alter their fundamentally flawed idea, as long as the currency can "pay for" itself LOL

Externalities. They have successfully externalized the problems they are causing on to everyone else.

The point that bears emphasizing is that Bitcoin is the harbinger of a new paradigm. It is the prototype of a technology and it's associated ecosystem designed to replace the current monetary model. There is no doubt in my mind or amongst those who closely follow cryptocurrencies that some other other digital coin with better technology will come along eventually and displace bitcoin. I agree this will take time, but it will not be a 'long long time'. Fiat may disappear almost completely in 50 to 100 years.
