To be practical your service would need to pick up laundry at all hours of the day and be basically “on demand”.

Cats puke on your only comforter. Kids spilled something on your fancy jeans. You need towels, stat.

That being said, if the service did enough (say put the clothes away organized and folded and had a turnaround time of a few hours) people would probably find ways to work around the shortcomings of using a laundry service.
