We have a system to address the public airwaves, which include all the airwaves on all property since the electromagnetic spectrum conveniently ignores our artificial property boundaries.
That system is called "licensing" and SmartCity is completely free to apply for a license to own their own slice of spectrum. When you are talking about single-building uses or point-to-point links they aren't even that expensive (unlike regional or national cellular frequencies for example). Good luck getting hardware makers to adopt your special snowflake system!
WiFi operates on unlicensed bands. By using such bands you are bound by various rules (like power transmit limits) designed to ensure everyone has shared access. WiFi itself is designed to scale down power and share transmit time to keep the noise low. In fact using a personal hotspot isn't likely to cause much interference since the devices are likely right next to each other and transmitting at very low power levels.
What you can't do is take the spectrum, protocols, and devices designed to allow everyone to share and hijack it to stop other people from using it.
You might make the case that officially certified WiFi devices should include some frequency bands that are license-only so that large venues could apply for exclusive use of certain frequencies* but unless and until that happens you are legally required to abide by the same rules as everyone else, even on your property.
* As radio chips get better it becomes more and more feasible to include the hardware for a multitude of frequencies (chips, amps, filters, etc); eventually SDR will make it possible to support a huge range.

In this context, (hotel internet) it doesn't seem reasonable to ask them to start manufacturing their own wireless cards that support a wider spectrum, since everybody staying at the hotel would need one.
We're not asking them to do this, just saying that this is what they'd have to do if they want to have a frequency that's protected from other users.
Right now, hotels have two choices. They can support cheap commodity equipment that uses unlicensed spectrum, but they have to accept that everyone is allowed to use that spectrum as they wish (within the rules) and this might impact the hotel's use. Or they can use expensive specialized equipment that nobody owns, and have guaranteed exclusivity to their bit of spectrum in that area.
I think a third choice would be great, to have commodity hardware that can access licensed spectrum so that venues who want to guarantee exclusivity can obtain a license while allowing their users to use standard hardware.
But that third choice isn't available, so the reality of the situation is the two choices above. Naturally, venues pick the option with commodity equipment and no exclusivity. And that's totally fine. But they can't then try to force exclusivity into the situation afterwards.
