This is how it has been in the past. But I disagree that it should stay this way!
I think this new fee structure would be a win, win for all. A fee that secures value accrual to Ethereum will give Ether the value to secure all the L2. L2’s can’t operate with the same security, if there is no such fee mechanism, unless we all believe in Ethers ultrasound “store of value”.
For Ethereum its better to extract some L2 rent, rather focusing on the wrong scaling theory (Scaling L1 for more Ethereum fees rather L2 ) and thereby implicitly charging a rent via higher L1 fees.
