That's not true, some buildings' management already handle this without a blanket ban. You can allow people to register their devices with the building, check for reputable brands and UL-listed components, and educate with rules and flyers throughout the building (that define where to charge, how to not use extension cords, be present while charging, etc).

I would also say that it's pretty easy to identify crapware from reliable batteries. Fly e-bikes, generic AliExpress stuff, cheap conversion kits, you can see those outright. Brands such as Lectric, Ride1up, Rad Power, are all solid. Scooters such as Razer or Ninebot, good. No-name scooters and hoverboards, bad.
