If you have a suitable machine to do so, then couldn't you just tunnel your DNS traffic through it and out its default resolver, without having to run your own?
The question would be why bother with 3rd-party resolvers in that case?
NB I have a slightly different setup - I run Unbound locally and route DNS requests through the 'suitable machine' on VPS over VPN established by my LAN router. I considered moving the resolver there but didn't yet found the setup what would be usable for me when I would be out of my LAN. Opening my resolver to the whole world is the way to be a part of the bot relays for DDoS attacks, so this is out of question.
