You can't just make an unsubstantiated claim of "asinine". I'd say the comparison is quite apt. Failure to enforce a condition can amount to tacit agreement to it - the same thing can apply in contracts.

Also a tenant in your situation would most certainly have rights to not be "unceremoniously kicked out" - both a time period before they'd even be legally expected to leave, and also legal protections against being forcibly removed even if they didn't leave at that time.
