I prefer running my own dnscrypt-proxy instance when setting up a network, it provides far better privacy than any traditional DNS server. You can configure it to cache all network requests, or even configure it to make requests over Tor so that it's impossible to log where your requests are coming from.
Aside from that, check out OpenNIC, it's a project aimed at decentralising DNS and letting people have more democratic control. You can easily get your own entire TLD if you've got the technical resources for it, plus it even has built in integration with Emercoin. On top of that, they also run some DNSCrypt servers so you can use both at the same time.
This just gave me a great idea, when I use my own VPN (wireguard) I could totally use this script you mention to send the DNS through tor for all my traffic right?
Yeah, it'll let you do that as long as you configure everything correctly.
You can also use iptables to just make tor your DNS provider, but you don't get caching if you do it that way so things will resolve slower.
