Sorry, the TL;DR wasn’t based on your message but my own. I was summarizing my reply. I should have labeled it “Summary” instead.

I remain confident that decentralizing Bitcoin by making more efficient use of block space will make it more valuable than it would be otherwise.

If we do nothing, roughly 10-20 million people can hold keys on chain. Everyone else will have to use some kind of trust-based layer on top. 10-20 million is still way better than the status quo (banking), but increasing the number of people with keys is even better, IMO.
