> Imagine if someone were to suggest that all web infrastructure should share the same database. That would rightly be seen as an absurd idea — but that’s what Web3 advocates are essentially suggesting.

I think BGP routing tables, ARIN, ICANN, whois records, and DNS root servers are equally as centralized as a blockchain would be - in that they form top level federations, sort of how "the internet" is centralized when you call it one thing. Cloudflare, Akamai, AWS etc are more centralized as single companies. Blockchains are essentially nested application/data layer federation protocols.

It's hard to respond with more charity than he ventured, so I'd ask if there is a smarter form of his argument I should consider. It may be worth hearing what the concern is rooted in.
