Why doesn't the city just run it's own scooter/bike share? Seems like it would exist in the same domain as things like MUNI and in theory would allow the city to make a profit instead of LYFT/UBER etc.
Some cities do. Denver has Denver B-cycle, and they are giving out 5280 free annual passes this year (not sure if they do this every year). The non-free option is still a fraction of the costs of the for-profit private companies. There are also a plethora of e-scooter brands though and I see them more often than bikes.
Boston has Bluebikes (e: seems like it's a partnership with Motivate?), also pretty cheap. A lot of people I knew in Boston had some kind of discounted rate through their employer where they got unlimited complimentary 30-minute rides.
Clearly you haven't taken the MUNI on a regular basis. The last thing we need is an incompetent government agency taking over yet another method of transportation.
