Getting tenure means (ideally) that the system considers you have proven yourself as a competent researcher and therefore accepts to release a bit of pressure on publishing to allow you to pursue more exploratory objectives. It does not mean you're allowed to behave badly and (officially) does not protect oneself from the consequences of such behaviour. Remove tenure and you remove the last bastion of real research we have left in our industrialized and quasi-corporate western research institutions.

Removing tenure would completely trash western science and in practice yield total scientific leadership to eastern powers, who still have old style academic systems with strong tenure positions and less concern for academic mistreatment and "wokeness".

There's nothing in tenure that requires universities to force bad teachers to continue teaching.
