It's definitely more efficient than driving yourself, but it's also hiring out your driving to someone else, which counts against someone being able to "walk everywhere" because it requires you to assume that the person can make up any shortcomings in their location with mail order. Point is, you can't realistically walk everywhere in most places.

ubereats/GrubHub is a notable exception, since people expect much stronger latency guarantees for this use case.
