In Paris and Berlin the alternatives are probably bikes, metro, or walking...
(I'll agree that rental scooter services have unique problems, but we shouldn't allow personally-owned scooters to be banned along with them)
In Amsterdam, my impression is that fat-tired e-bikes have become the standard replacement for mopeds, which I think is an improvement.
In the UK, personal scooters are still illegal, and the problems with rental schemes seem to be being used to keep it that way :(
