Only a few hundred million people will be able to use lightning directly self custodially because of how many channel opening txns can fit in a Bitcoin block Others will be inevitably pushed to use trusted/centralized systems So many Bitcoiners don't want to acknowledge this fact as if lying to themselves will somehow fix this

Can anyone more knowledgeable about statechains and Spark comment on this? I was trying to understand how Spark works and I think I came across the fact that, to unilaterally exit the system, you can't just broadcast one onchain txn or a fixed number of txns either. You have to make n + 1 number of txns if you don't want to co-operate with the Spark entity, where n is the number of times the leaf (offchain UTXO) has changed hands. That means, since the initial onboarding txn by someone, if you are the 20th recipient of a Spark UTXO, to unilaterally exit you'll have to make 21 txns onchain. If that's correct and there is no way for the exit txn chain depth to be reset, then Spark is completely useless as an "L2", and you are better off just using Liquid or Cashu. I hope I'm wrong though.
