The only things EV's solve is emissions. They reduce emissions in cities which is great, and thanks to clean power plants (renewable and nuclear) help reduce overall emissions. But they are still cars, still take up space, they are heavier so cause more wear on the road surfaces and emit tire particles. I wouldn't say these are tiny issues.
If we have to use cars then yes, electric are better, but it's not the solution. The solution should aim at reducing use of the inefficient forms of transport in favor of mass transit or micro mobility.
False dichotomy. You can rent a villa, summer home, or any other non hotel accommodation outside of Airbnb. We used Booking.com for our last holiday, and the same place we rented was listed on Airbnb but more expensive by about a quarter of the price.
