Yeah, I have thought about that, and I also think it may be intentional, for the reasons you mention. But it's quite ugly that in order to implement that "endorsement system", they push you to lie, because both the letter of the law and the forms that both the immigrant and the "helper" person sign are quite unambiguous: you are declaring that the person physically lives in that address, which is not true. If they want an endorsement system, they could explicitly create one.
