If you read the first sentence of the white paper, you don`t get taxed, there is a network fee, which is kind of like a tax, but not really a tax.

If you use bitcoin correctly there should only be 1 fee when trading.

So there was no need for satoshi to mention anything about tax.

In the future I would like to see the network fee kind of support other things not just the miners, you could build a real society behind a model like this.

Imagine everyone voting where the tax fees were spent in your society and everyone creating the supply rather than a few, it would be like a non communist $lavery $ystem for once.
