You can't take a bike easily into: a car, the subway, your flat, a shop, ... It could also be the same reasoning as a car regarding the space: a bike for 1 person takes more space than an e-scooter for 1 person. The real problem is not the device: it's the users. People using bikes also do stupid things, but not that often. Bikes can be very fast too, with electric assist they can go faster than cars in the city, but most "problems" seen today are with the scooters. This is a sad situation, but it's some users' fault, not the operators', not the city's, ... One way to deal with this would be to have a license to drive a scooter or bike, so that kids (and adults) are taught some basic rules and have to follow them. But I guess this is politically hard to implement, it's easier to ban.
