"Persistent" reputation won't change that. Because on the internet nothing is persistent, without a central party enforcing it to be so. And as said above, the ones in charge of it now, don't want to enforce it really. You don't own your domain, you don't own your IP, you don't own your feeds, "content" etc. The infrastructure that routes people to your correct "reputation", isn't yours, it's controlled and owned by Big Tech, governments, and some smaller companies. Your feed can be taken offline or away from you in a whim. Access to your blog isn't yours. Not even if you host it on a rasberry-pi in your cupboard.
Aside from maybe some blockchain shenanigans, that is. Bitcoin and maybe Ethereum are the only decentralized "pseudonymous" identity providers that could step into this, but both are ridiculously costly and complex. And wholly unsuited to route content. Systems designed for this, like Tor, aren't really up to the task either. Just look at how insanely hard it is for "Content" that governments oppose, to remain online (e.g. on the tor network). Possible, but so complex, so fragile, that it's not a practical system to use en masse. Yet it's the only working system that comes closest to really owning content in the broad sense.
So it makes perfect sense to turn to the systems that have done this "persistent reputation", aka "identity" for centuries now: Governments. Compared to Big Tech, they're more decentralized - there are far more governments worldwide "doing identities" than there are FAANG corporations. Hell, even within the US or within my country alone, there are more. Compared with all other systems, we can control them, push them into a direction we want them to go - democracy. Far from perfect. Bad even. But the least worst way to have some "persistent identity" we can get. Unfortunately.
