Bicycle road rage does exist, between road bikers and regulars, between fast electric and regulars and in general because plenty assholes do also ride bicycles if the infrastructure is good enough.

Other than that, all valid points!

It’s very young and got very popular suddenly, someone will make a nice stable UI for it at some point…

In some situations they’ll rather have empty houses than rent it out to the poorest people for lower prices. Or actively destroy (“upgrade”) affordable housing to keep prices of the rest up. And if the prices do really go down a lot it’s still poors with mortgages but suddenly no more enough income selling their places for bargain prices to the ultra rich for whom even in a real estate crisis with crashed prices it’s all still just a game situation, not a food on the table one. They use it to gobble up even more.

There is plenty of housing currently in Western countries, it’s just not being made available to those in need. That won’t change with lower birthrate, it will stay not available to them. It can only change with system change where no one can hoard insane billion amounts of $ € ¥ numbers on their screen or have thousands of homes as their belongings.
