Your analogy doesn't hold up very well. There are rentals that are restricted much more than your average apartment, they are called hotel rooms.

There are different options available, because there is demand for it.

The same applies to ISP service. In general residential service is over subscribed. This allows the company to discount the service in return for restrictions on how it can be used.

There are also dedicated bandwidth options, which are much more expensive. But you can use it pretty much however you want.
