Not just cargo bikes. I've got a folding bike (small apartment) with two panniers and a backpack. Sure it's not car level but its pretty good for grabbing groceries.

And it should be noted, Columbus has a pretty bad food desert problem.

And if your cargo bike got a flat while you were at the grocery store? It's nice to have friendly neighbours to help out.

Ah yes; the cargo bikes everyone carries in their car when they have to lug a ton of groceries home

With the post indicating that it was a kid’s birthday, I thought the same thing. They may be buying supplies for an entire party. Walking home in summer heat carrying a cake (that should probably be refrigerated) doesn’t sound easy, but add in the kids (are they big enough to help carry things? Or are the kids so little that they need to be carried?) and the rest of the supplies the family bought, and it easily adds up. Then we have roads that aren’t designed for walking, no public transit options, and who knows how far they had to travel to get back home.

If it takes you 3 hours to walk a return trip to the grocery store, you don't just live in run-of-the-mill car-centric design, you live in an absolute barren food-desert hellscape. Which is precisely the sort of thing people in this Community advocate against.

I mean, that's certainly not a reasonable amount of time.

Why would you need to carry 5 gallons of water or half a cow of meat? Are you living in the post apocalyptic world? You typically get water from the tap in your house and buy meat from the cow pre butchered.
