>Cryptocurrency is a nice idea but there are and have always been too many gas fees for anyone to sensibly use it. I want to buy something not support everyone that get their hands in my transaction chain.

But you're doing this with credit cards already? Different amounts, but still supporting everyone in a chain. If you want to "buy" something without supporting intermediates, then barter is the only way to go. Everything else requires common trust, and common trust comes with operating cost.
