You’re making a lot of specious arguments. I think your laymen’s logic checks out just fine here but that’s not how aviation works…and for good reason.
Taking off with 1 of 2 engines is a lot different than taking off with inoperative avionics. The FAA and airlines dictate what minimum equipment is required for any given aircraft to be airworthy and it’s a fairly robust document that takes into account myriad situations and flight conditions.
