Well because in the example i gave you this decreases the miner's reward. The rule of increasing feerate you stated isn't always economically rationale.

Note how it can also be extended, for instance if the miner only has 1.5vMB of txs and is not assured to receive enough transactions to fill 2 blocks he might be interested in maximizing absolute fees, not feerate.

Sure, we could make the argument that long term we need a large backlog of transactions anyways.. But that'd be unfortunately not in phase with today's reality.
