True, but its best to do it with large pools of funds.

ie. payment privacy for like $100 to $200 is easy on lightning, but if you have savings of like $30k, you should CJ it and only send to payment wallets or pay out to others in smaller batches. Yes this adds to UTXOs, but not to an extent that should be a problem in the next decade. $10 to move $10K is cheap.
