To set up a "wireless" solution requires a housing, microphone, speaker, volume controls, nowadays some sort of digital logic to find a channel and minimally encode/encrypt it enough to get past any rf noise in the air, a battery plus an associated charger setup, a wall mount for the classic intercom position...going to cost more than we want it to cost.
Most people don't have the skills and/or feel the challenge is too great for running some low voltage wiring for a new setup, which is why wireless is so desirable.
(PS if you ever get a chance - put conduit/raceway/pullstrings/blanked out boxes EVERYWHERE, because you are going to want low voltage EVERYWHERE later on)
(PPS heck wouldn't be surprising to see whole households being wired with low voltage overhead outlets within 5-10 years. Skip tiny transformers in each bulb and just a few large ones for each lighting circuit. Already happening in commercial areas. Heck I look around and really don't need many full power outlets nowadays.)
(PPPS Have done low voltage lighting, paging/speakers including running them on cat-5, security including PoE cams, nurse call - again with modern systems on cat-5, etc etc. Huge portion of the stuff is just transitioning to use Cat-5e as a universal base wiring method.)
