DNS question - why using a recursive resolver (e.g. 1.1.1.1 or your ISP's) instead of running it locally and querying directly the DNS root servers?

I couldn't find an answer to this one. Negate says on the pfSense docs that the resolver (unbound) that is installed and enabled by default ignores any recursive name servers set and instead query the root servers directly, unless configured otherwise. (https://docs.netgate.com/pfsense/en/latest/services/dns/resolver.html). So I was thinking, in a privacy point of view, why having an intermediate and send them all your browsing history? Cloudflare implements, for example, DNS over TLS, DNS over HTTPS and even encryption of SNI (so "your ISP can't really see the names you are querying"). But ISPs can see the IPs you are accessing and, therefore, can trace back the IPs to their corresponding names. It looks like a bogus sense of privacy only to convince the users to send them their DNS requests. Besides, running it locally could bypass censorship on the DNS level (yes, it happens sometimes in my country, very "democratic") and the local cache could not only speed things up but also really improve privacy by reducing the number of queries sent though wan (and, obviously, excluding intermediates). Idk, maybe I am misunderstanding the functionality of the DNS stack. Am I missing something? Could someone help elaborate? Thanks!
