There will be so much government resistance when btc hits a few thousand per coin, let alone multiple thousands per coin. So many things would need to fall into place for us to get above probably 2k. The numbers we are talking here would be like literally replacing the currency of several first world countries
The government cannot stop this.... at all. A mere next bubble can take us there should we cross the chasm. I think it's still too early for that, but I generally lag Bitcoin's progress.
