For anyone that hasn't been to China: the bike share bikes don't have a docking area. People can park them wherever they finish with them. They have a little lock on the frame that stops the back wheel from moving until you scan a QR code on the bike with an app, then it unlocks.
Given the huge bike theft problem where I'm from (London) I don't think that system would work because thieves would just pick the bike up, put it in a van, and break the lock later. It probably happens in China too, but apparently not enough to deter the companies from doing it that way.
It works because the bikes have very different frames compared to normal bikes, are easily recognised and therefore worth little to nothing on the black market.
Vandalism is a much bigger problem than theft. I haven't heard of theft of these bikes being a problem at all.
In Bristol, UK they recently started a bike sharing system that didn't require docking but had issues with theft and vandalism so they had to change plan and introduce fixed parking spots. They even cancelled the service in part of the city.

IF you're talking about bikes being left in the way of pedestrians, I haven't experienced it, and I'm sure you could get people to think a bit more if needed.
In any case it's magnitudes less of an inconvenience as that currently created by cars. Considering that about 2/3 of people in central Berlin don't own a car, there's really no reason not to compare the status quo with city almost free of cars. It would be drastically different, as you could reasonably double the space available for the public: eliminate two lanes of parked cars, and make most streets one-way. Most traffic lights could be eliminated, biking speed would double without waiting for cars and red lights. There'd be space for almost anything, from small gardens to sports, right in front of your house.
Other thing is that there is also NextBike alongside Lidl-Bike and that is a bit unfortunate.
