Because what matters is the impact on other users. OpReturn isn't in UTXO space and doesn't even take advantage of the witness discount, so it clearly has minimal impact.

Since it has minimal impact, there's no reason to micromanage exactly how people use it. Let them decide for themselves with the fee market. This is exactly the same as how we didn't put artificial limits on Taproot.
