I'm not sure where you got the "I don't understand this" and the "This is dumb" interpretations from. It's pretty clear that neither of those are expressed in that comment. There's one coherent idea that is expressed, and it could perhaps be summed up as, "This idea is not particularly innovative or special in any way."

This is really no different from ordering pizza. I mean, the ingredients even overlap to some extent, although most pizza vendors will also offer drinks, sandwiches, chicken, and other dishes these days. And basically every pizza vendor will deliver to your door.

Many of the larger pizza chains have at least some presence over very large areas, so you can get the same predictable meal even when in distance cities or towns. And these days, most of these chains offer various ways of ordering, from in person to over the phone to websites to mobile apps.

Sure, it takes some skill to get such an operation up and running, but the idea itself isn't new by any means. And there really isn't anything special about it. It's just a very, very slight twist (perhaps even just a simplification) of a well-established type of business.
