You tax land, you tax imports & exports, you tax people coming & going, you tax the cars, and you tax the planes.

Governments will still be able to operate & be able to tax their slaves citizens. Cryptocurrencies may make governments a bit smaller and leaner, but they won't get rid of them.

Bitcoin will allow us a better way to send money around the world for just pennies and allow the storage of wealth in cyberspace. It will allow people an easier way to flee the worst governments.
