A significant percentage of the population can be manipulated to support anything, but bitcoin is a consensus system. Hitler did not manipulate 100% of the population to support him. There were many who refused, and who actively acted against him. There was not 100% support for any of the wars in Iraq or Afghanistan. All of those wars had individuals who publicly spoke out against them.
What percentage need to support it? Is a majority of full nodes sufficient?
When people get new bitcoins that aren't spendable in certain locations, it will be interesting to say the least. Then the government will force everyone to "accept all bitcoins".
