But full decentralization would break every major website, not to mention countless smaller ones. There’s a reason CDNs like Cloudflare, Akamai, etc. exist. Websites for retailers, banks, healthcare, etc. would all be useless without them. You’d be lucky to load one page an hour on your banks website if they didn’t use a CDN.

Edit: whoever gave the drive-by downvote care to explain why I’m wrong?
