You are describing something functionally on the same scale as to the "extreme blowback" rich people get when people make fun of them on Twitter for, say, burning untold amounts of dead dinosaur goop to make an NFT or to not quite go to space as a personal stunt. It is somehow, however, though not the "economically just circumstances" of the hand-to-mouth mom. Which is a situation to which I will confess some confusion, but whatever.
I'm sorry - I don't think we should build a million skyscrapers in Kethum, Idaho and Jackson Hole, Wyoming so that tourists can enjoy it more cheaply.
I do think we should build more housing in major cities.
[0] And I would expect those units to not be evenly distributed around a city; there will probably be higher concentrations in the more touristy spots where this community stuff matters less, and lower concentrations in the more "sleepy" residential areas.
Why ban just AirBnB and not Waze for bringing unwanted traffic in previously quiet neighborhoods?
A tourist is fundamentally there for temporary and consumptive reasons. They don't have any long term interests about the place they visit. They are accommodated as guests. As such, it is only rational that they don't receive the exact same consideration as the residents who have their skin-in-the-game of that same place.
It's better than sleeping in your car.
Without the Airbnb, where would we have gone? A hotel? But a hotel with a useable kitchen and good wifi would have been too expensive for any of us renting one of those rooms.
And let's not assume that anyone who wants to list a property on Airbnb is mainly motivated by greed. Attempting to paint the people on the other side of your argument as evil is a pretty transparently bad argumentation strategy.
