Every few weeks there is enough liquidity registering to https://coinjoin.nl 🕶️ but I’m in no way useful to the people that want to anonymise 100+ BTC, as my typical liquidity is several million sats with ~4 anonscore.
That's a problem. Looking at the nostr:nprofile1qqszfn67p6jlle0qsj7lwx2l0ylxpse83e0x56qe5euxtwgwnyzdfqgpz4mhxue69uhkg6t5w3hjuur4vghhyetvv9usz9thwden5te0v4jx2m3wdehhxarj9ekxzmnyqyxhwumn8ghj7mn0wvhxcmmv8xlnk8 coordinator for example, it seems it would be enough to have 2 or 3 more extra people to bootstrap it completely.
You won't gain anonymity but a level of privacy enough to make it hard for most people to track you.
There is a centralizing force, yes. But it's also some convenience in decentralizing the liquidity and it would also be good to use smaller coordinators.
