Strawman. Free parking is perfectly fine in low density non-commercial neighborhoods. The problem is how AirBnB enables commercial use of residential property.
Like most people in the US, I live in a neighborhood of detached single family dwellings on their own lot. Paid parking is even less viable than frequent efficient public transport. The actual development density is about 15 persons/acre or about 37 persons/hectare net for the neighborhood. Considering the surrounding development it's less than half that.
