either you pay for docks, or you pay for digital active devices to pinpoint dropped bikes. Its cost. So, this is a cost shifting debate.
I use docked schemes in my home city. I obviously realize the pain of the walk to and from a dock is a problem, but at scale it feels like the benefit of docked bikes outweighs the consequences of community damage from undocked bike litter.
So, yes. if you cost the locate the bike and drive to making it less like dumped shopping trolleys its good, but then you accepted the cost exists: the profit model for many bike schemes is to try and cost shift out of this, and not care.
Avoid litter: use docked bikes.
