The large majority of tenants do not read their lease paperwork carefully enough for this clause to make a difference.

A large majority of humans don't read EULAs.

A lease clause is useless for liability, because your landlord's insurance won't be able to shake down the tenant anyway.

Someday soon enough, your insurance might require a clause like that. It will still be ignored by tenants though.

And the "intelligent" part makes them realize that you get absolutely nowhere if you try to strictly follow all rules (there's a reason why "work to rule" is an effective sabotage strategy), and that the path of least resistance is to sign and ignore it.

It’s not unjustified. I’m a tenant. I don’t read all of the clauses. I’m a normal well meaning intelligent person. Does not change anything about what I said.
