I don't know why people downvote this. There are two problems when you have a democratic system of government (the US is no longer really a republic IMO):
1. Special interest groups
2. Involuntary taxation
The two combined make for some quite uncomfortable moral hazards. If you pay taxes in the US, you are paying for continued aggression. Or education you'd rather provide yourself. Or any number of things that you don't agree with. For every citizen, there are just a few government services they use over and above the common services everyone else uses as well (not listing them, numerous).
The majority of money that the government collects from the citizen is not spent on the citizen themselves.
"Sure", you say, "It's to help the poor!". As Milton Friedman said: if government could solve the problem of poverty, then why are there still poor people?
In my locality, there are instances of local governments spending $60K per poor family of four annually. Only $20K actually got to the family. The rest becomes overhead.
I think it's quite valid to say that the government should not be involving themselves in commerce in this manner because then they become indispensable. Not because they are useful, but because then they fund a set of uneconomical businesses that no one else would invest in.
TL;DR: don't downvote because you don't agree.
