I mean, the relative cost really depends on how much you value having one up that you control, I suppose.

I also think Pleroma or one of its forks (Akkoma, etc.) might be far less hassle to run while still being compatible with the same metaverse protocol, because Elixir (with erlang/OTP underneath) is far more resource-efficient than Ruby is (we're talking orders of magnitude more efficient in both CPU and memory efficiency, although content storage demands would likely remain necessary to keep a lasso on)
