This is a bit like saying hotels are obsolete because most of the time you live in the same place and apartments make more sense.
The value proposition of a scooter service is ad hoc last mile transport where you don’t have to have brought the scooter with you to use it.
There may still be issues with the model. It might be that isn’t a demand profile that has the right scale to support much of a business (but could be useful for municipalities to provide, like some do with bikeshares). And I find rideshares are price competitive for last mile stuff (though it’s well known that’s only because ride costs are subsidized with investor cash, so maybe all scooter shares have to do to find their market niche is hold out til that stops). Or maybe most people feel safer with other forms of transport.
But the basic “summon something better than walking without having to carry it with you” idea does make some fundamental sense.
For me, a scooter is much more affordable than say, a hotel. I am willing to pay a small premium in rent over buying the hotel for the convenience and flexibility of not having to own a hotel.
I am fortunate enough that there's no way a lime makes any sort of financial sense for commuting last mile in a place I live. I can buy a scooter for $500; I will break even on Lime/Bird in less than 3 months. For tourists, great, for denizens, not so much.
The simple fact is, unless you want to pay for the luxury of having to walk to a scooter you pilot yourself, owning your own things has always made more sense. The ability to semi-summon an object on command is great when you need, and can afford, the option. However, we should be optimizing infrastructure for everyone, not just those who can pay for it.
Scooter shares may indeed not make much sense for commutes. That's the sort of predictable and regular need that it makes sense to optimize for time or money or both, as you've said. But then again, rideshares are rarely going to help with such optimization (probably true as long as funding a driver is part the whole thing). Personal vehicles, or public transport, or even workplace carpools make much more sense there. And yet rideshares do well enough because it turns out there's a whole class of ad hoc transport needs where summoning a ride on demand is awfully convenient.
Acquiring a scooter on demand has the same possibilities, especially if it can be economically competitive.
