So what do you propose if you hate the government?
This is an incredibly loaded question, bbc.reporter
There's no mention of hate, simply statement of easily verifiable facts. These may be unpalatable facts to some, but it's entirely correct to say that police in pretty much every western "1st world" country behave oppressively towards members of the public that they should in fact be protecting from bullying behaviour. The problem may be more serious in the USA, but it's happening on a small scale everywhere.
What should we do to start governing ourselves better and how do we create a better system?
Be the change, etc. With Bitcoin, we're already doing something very important, using a private system. Try to live your whole life without using government services, and encourage others to do the same. If no government will ever honestly decrease waste and corruption in public services if they are voted for, then we should vote instead with our money for services that are properly incentivised to serve it's users.
I reckon the problem with the government is not about collecting taxes. From what you mentioned, the problem is a country becoming a police state like what is happening in America now.
All states are police states to some degree, as they all rely on threats, theft and violence to ensure people pay for government services.
The magic is in how this has evolved; as recently as the middle ages, governments didn't even try to pretend that they weren't bullying people to steal from them, taxes were collected exclusively for maintaining the position and lifestyle of royalty and local lords. But as the education of regular people became more widespread, and possibilities in infrastructure and industry improved, government gradually changed itself from the previous system of obvious open theft into a more benevolently styled system. It's no coincidence that the power of the church simultaneously waned; all the best liars could earn a more attractive wage constructing lies for governments than they could as church ministers. The psychological control of the masses switched from church to state.
The truth is we never needed them. Most people treat each other well without the threat of state punishing them, they value their reputation (and simple reputation is a more effective policing system than ever in the internet-age). We're paying alot of money to the government for very little improvement in our own lives, when we could simply pay for what they do provide (far cheaper than the corrupt deals they make) directly.
And we can avoid paying them to start fights (i.e. wars) with other governments that threaten everyone's safety, and in the end only serve the needs of their friends who pick up all the contracts to rebuild the destroyed cities or to steal the natural resources from the previous owners exploiting them. Or you could just believe all that BBC reporting that says governments invade and bomb other countries to pieces because of what nice people they are.
