The brilliant thing is that you can stack. In other words, why would I want every transaction to be on the blockchain? I could just as easily use one of the more than 50 2nd-layer "Lightning" wallets and seldom touch the layer 1 blockchain.

I think some of the recent events around FTX and similar are exactly why you would want on-chain records, fees or not. Actors in this space are (imo) not fully trustworthy.
In the case of Ethereum's zkrollups, all transactions are on-chain in compressed form and fully validated. You're not trusting anyone to custody your funds.

So with very little risk you get:
BTC = security, performance, decentralization.
