Average people don't really care that much about "been controlled" by ? and ? and ?.
They do if that control prohibits them from freely using their money.
Controlled currency: Someone else imposes fees on you, tells you when you can pay, how much you can pay, imposes restrictions on who you can pay to, and can even take back money paid to you already.
Look at the sexual harrassment coming from TSA agents. First in airports, soon in bus stations and malls and then on the streets. If you accept that, then I think you accept anything.
When 2 people have a bitcoin wallet, money will travel freely between them.
There is nobody to tell you what you can, or can't do with your money. If you have it, you can pay with it to anyone who accepts it.
