technically it is possible, but politically devs just say no with some lame trumpesq excuses
'2015: hard drives will fill up fast if we had 2mb'
'2015: we want segwit and it will use 4mb bloat but not achieve 4x scaling, dont worry hard drives will be fine'
you're being disingenuous and you know it. you're ignoring the quadratic hashing problem. segwit specifically fixed this and expanded block space for transactions that don't worsen the problem. you also know this was done as a compromise so bitcoin could have bigger blocks but still allow for large-transaction use cases. the best of both worlds in other words, vs a crude sigops limit:
Removing the quadratic scaling of hashed data for verifying signatures makes increasing the block size safer. Doing that without also limiting transaction sizes allows Bitcoin to continue to support payments that go to or come from large groups, such as payments of mining rewards or crowdfunding services.
