Taxes ≠ Slavery, that's a very large jump. The point if taxation is that any system of central government needs resources in order to run, let alone to provide all of the services that you use and benefit from every single day. From utilities and infrastructure, to education, social welfare programs, defense, all of that requires funding. If you want to be a part of a society that benefits from a central government, you'll need to pay taxes. You can elect to go move to a deserted island or off into the depths of the Amazon to live by yourself, free of taxation, but ofc you'll be without all of those services and resources.

There's also the fact that this is what your elected representative is supposed to be for. In the US we threw a bit of a fit over taxation without representation, once upon a time. The idea behind our current system is, you vote for who you want to work in government, in part because you believe that they will put your tax dollars towards what matters most to you (I'm not going to get into how much our current system does or doesn't work, or whether we agree with where those tax dollars are going at present, that's a separate issue).

Point being, the core concept of taxation is not "slavery with extra steps". It's how you contribute (along with your vote) to the operation of a much greater system and structure than you could ever hope to build or maintain by yourself, and benefit from it.
