The average user is not capable of running that themselves. Your ISP can potentially see queries if you do this also, so if you don't trust your ISP, or worry about what they may be forced to do by your government, it may not suit. Further, DNS really benefits from caching as it scales up. As someone who runs my own resolver locally myself, I can attest to the sometimes long delay to resolve a hostname (requiring multiple external requests as the tree from root server is recursively queried). I still run my own recursive resolver, I find it the best option overall, so ultimately I agree with your statement. But like anything there are trade-offs.
