Looking at taxes as a partnership is more appropriate. The government sets up systems that help you make a good business, for example a good financial system, a good law and order system, good infrastructure etc. These things help you make the money. So the government is a partner with anyone who uses these infrastructure to make money and in this partnership there is a sharing of profit which can be understood as taxes.
That would be fine if it were voluntary. But you cannot opt out. If you try to opt out, you go to jail.
I didn't ask the government to do any of that for me, and I would prefer they didn't. I can't fix someones car without telling them, and then demand payment.
Our government has done a terrible job at infrastructure and I hardly find it unreasonable to believe that I should be allowed to hire people I choose for my needs.
If I wanted an exciting life full of collapsing bridges, sinkholes, and trigger happy police, I would gladly hire government. I'm dull though. I prefer things to work the way I expect them to, no surprises for me please.
Do you think its reasonable that government takes less from you if you commit suicide than if you renounce your citizenship?
I never agreed to be a citizen in the first place. Why should anyone have to give up everything they have just because the government decided to auto enroll them into a system without their consent?
You didn't ask to be born. Humanity has done an absolutely terrible job of managing this planet. It's not fair that people have no say about being born into it.
Only a very small fraction of tax revenues are applied toward this helpful infrastructure. The majority is used to fund useless wars and other special interest groups - hardly a mutual partnership.
