The analogy is just that, an analogy. The Airbnb case can be tragic for some cities but for specific reasons that aren't going to affect cafés. I for one haven't seen anyone staying overnight and sleeping in a café.

The project could be catastrophic for cafes for unforeseen reasons, but those are surely not going to be the same as for Airbnb. You'd have to come up with a plausible threat scenario, otherwise your extrapolation of the analogy has no substance.
