The fact that you have to take a wireless one with you is just one more
thing against it.

... or for it, not everyone has either a tiny house or wants
a bell system that loud, which tends to be that much louder
in areas adjacent to it.

If you can't hear a bell throughout the house, why bother with one? Just
have a knocker on the door - no batteries to go flat and no running costs.

If you have plaster walls or
teenagers/others with loud stereos you may also find there's
no one bell system that can be heard everywhere without
waking the dead in the next zip code.

In short the ideal bell system is not as loud as possible,
it's only loud enough to be heard reliably. One could wire
up secondary chimes but considering the addt'l time and/or
expense it may not not suit all needs either.

It's such a one time installation worth getting right, IMHO.

You don't "have" to take anything with you, that's like
claiming it's a negative thing that a notebook is portable.

Not a good simile. You find a notebook when you want to refer to it. A
doorbell is needed at random. And it's such a random thing the idea of
carrying it with you strikes me as silly. If you did need such a feature
one which interfaced with your mobile would make more sense. Easy enough
to do with an alarm SDI if you wanted to.
