And there are people who have to do the same difficult, time-consuming and demoralizing work acting as gadflies against the egregious abuses of multi-national corporations.
And the notion that Governments don't compete is always either false or double speak. It either is the case that governments compete with the private sector (e.g. government backed plans for health insurance can operate more cost efficiently than the private sector, so they're a problem), or they don't (as you've just claimed).
And there are opportunities where people have successfully competed against governments as well. Governments collect mapping data and you can pay for access to that content. And yet there are tons of mapping companies out in the world, many of whom have better services and capabilities.
Lastly, for people who might wish to claim that government can wield undue influence over free markets when they get involved in industry, nothing has stopped them from getting involved in industries they're not directly involved in. The federal laws banning online poker are a great example.
Industry lobbying is such a powerful and distorting force, again enabled by a lack of transparency, that it seems laughable to be worried about undue government influence.
Can you please point out some of this many oligopolies that somehow force me to do business with them? I can not buy from pretty much anyone I don't like, if I avoid paying taxes I will probably end up in jail.
Your participation in government and society is still contingent. If you don't want to pay taxes, go become a monk and take a vow of poverty (yeah you will still have to file returns, but whatever).
If you participate in society, you are going to have to pay taxes. Just the same way that if you want to get access to the internet, you will have to pay a company like comcast.
And, when it comes down to it, the oil and automobile companies, as a practical matter, have done a pretty good job of ensuring that Americans have to have cars, and have to pay for gas in order to live in society. That is for all intents and purposes the same thing.
