I think so. I would make two bets about where we’ll be in 10 years and am trying to figure out the implications:

- Block space will be massively more valuable than today, as tools built around digital permanence become more prevalent. Almost all monetary transactions will be fully ‘packed / joined’ with many inputs and outputs, which spam transactions of today don’t need to compete with.

- Mining will be massively more decentralized than today making it harder/more costly to route around nodes.

I dont think the second one matters so much as it relates to spam, as we only need a small minority of nodes to propagate transactions based on likelihood of mining vs a qualitative assessment of what’s inside, in order for it to be mined.
