Okay, so I disagree on a few points here, which I don't think you've substantiated.
A government without the ability to use force, i.e. specifically to tax, is a government incapable of allowing businesses monopoly and thus the ability to become rich in the first place; this means, without the government to tax the rich, there wouldn't be any rich for there is nothing to shield a corporation from unethical behavior and nothing to allow a corporation unfair practice among their small-business competition.
Perhaps I misunderstand what you mean here, but it doesn't take any force to
allow something to exist - the government I just formed in my garage can do that. It takes force to
stop monopolies from occurring. It's a classic problem of free market economics - the best, most innovative company achieves a market advantage, then they can afford to sell at a loss and force competitors out of business if they want to, then they have a monopoly. Governments don't always succeed at stopping this, but to claim it would never be able to happen if there was no government is absurd.
Without this use of force, people would be able to work without the expensive governmental overhead, without the laws which steal from the poor to give to the rich in the first place (which effectively removes the need for you to, again, steal from the rich to give back to the poor who would then be stolen from again thanks to government), meaning they would make more and could work less, which means they could afford food, housing, clothes, health care, education, without the need to steal back the money taken from them. Instead of taking from the people to take care of the people (with all the government waste in between), the most practical, cost-effective and humanitarian approach is to simply not steal from the people in the first place.
I'm not sure which country you live in, but could you point me to an example of a law which actively steal from the poor to give to the rich? Your basic premise seems to be that government is the only thing that enables the rich to take the wealth of the poor? I think the rich manage to do that perfectly well on their own. I would agree that governments regularly fail to stop the poor from being exploited but again, why would this get any better if there were no government?
Furthermore, I detest your skewed representation of "rights". A right only functions when the parties involved agree upon them and agree to defend them; the idea that rights are granted by government is akin to saying that nobody has rights but what the masters of a given society allow them to have, which do not count as rights, but only as privileges, as you mother and father would give you when you're young, or, as mentioned, the owner of a pet.
I don't believe that rights are, or should be, handed down from on high, and I don't know what I said to make you think that. It is self-evident that rights only exist if some-one defends them and, like it or not, it takes force to do that. It's all very well to say "each party will agree on their own set of rights and defend it themselves", but who will defend the rights of the weak, or the poor?
Instead of viewing the poor as a bunch of animals that must be cared for by the rich pet owners, why not take your foot off their throat and let them help themselves? Why do you agree with the horrendous practices of the rich whilst simultaneously claiming you're trying to help the poor?
I should probably say at this point that I have been desperately poor in the past, and I obviously don't think it's because I was an animal. I did help myself, and a government-funded education system paid for by the citizens of my country helped me do it. There is a foot on the throats of the working poor my friend, but it does not belong to the government - it belongs to powerful corporations, and wealthy individuals who hoard wealth and property. At worst the government doesn't prevent the theft, but it's not the burglar.
