First you don't **have** to consolidate. coinjoin / payjoin features can be implemented in the future to address this concern, but it's not an issue in almost the cases if you use your wallet frequent...
So if you have let's say 20 UTXO which you didn't spent from you just do 20 separate transactions after one year at the same time? Isn't it very obvious that the transactions come from the same wallet? Also it's 20 times the transaction fee in the future which is very uncertain, right?
