Why not ZeroTier?

It seems too centralized. At that point why not use a VPS? I have a free vps from oracle I already use to relay some unimportant services to a static IP. But it's extra latency

I also run monerod, p2pool, i2pd and tord nodes, the purpose of which is defeated by central infrastructure.

But yeah friends have reccomended tailscale I have just never gotten fuzzy feelings whenever I revisit it. If we want to build a NAT-less world then everyone needs to get a static ipv6 and run an eepsite or onion service, and we can just use pubkeys for addressing.
