>Because (1) a jammer is an unlicensed transmitter and (2) jammers do not just jam with discretion they jam for as far as they reach and it is impossible to operate a jammer in such a way that you cover all the territory without extending beyond it in some places.

Jammers can interfere with people's ability to contact emergency services. Obviously in the case of WiFi this is not an immediate concern because 911 is currently reached through a different wavelength, but WiFi is integrating into infrastructure (WoT, etc...) such that jammers can be a real cause for concern (especially if they are operated by poorly trained people).

What about the scenario where you have an ISP that offers city-wide WiFi to its subscribers. A Marriott is within the bounds of this area, they block access to a service I pay for and they have approval to provide me with. Who is in the wrong?
