**LOTTA CAPSTYPINGS***
Happy Saturday!
Just to be clear, you seem to be stating that a future where transaction fees being $100, $1000 or even more per on-chain tx is a distinct possibility?
That as a possibility is implicit in my thoughts, I'd say, yes.
OK, so here's the relevant followup question. When average tx fees are $1000, what is the typical profile of a person willing to run a non-mining validator? Let's start simple on this - how many tx per year might the average such person make?
It could be just one or two, but sure it won't be peanuts. Running a node still makes sense in such a case.
