That's a great idea if your kid is less than 15 pounds, but it's very hard to wrangle a willful 2 or 3 year old the 100 feet across a busy parking lot and back to the car without picking them up which is a monumental task for many people. My wife has this issue because our son is more than 30 pounds which is very heavy for her. Every kid is different and people don't always have the same physical abilities as you do.
You had to get your kid out of the car and bring them to the place where you picked the cart up at the beginning. Typically the cart return is closer still.
Most 2-3y old kids can walk and when my babies where too small to walk I would just put my groceries in the bottom part of the stroller and in an hiking backpack instead of a cart.
Sure, but my entire post was about safety issues having my son walk in some parking lots. And getting my wife to put on the equivalent of a 60-liter backpack to go to the store is absurd.
I get that you don't want to make accommodations for people but you might want to think about what leads you all to get so bent out of shape on this one. At the end of the day your argument boils down to "your spouse just needs to work harder so I'm not inconvenienced by the cart she hung off the curb next to the space I wanted." Society is full of people with differing abilities in differing mental spaces and not everyone owns equipment like that and is willing to spend 10 minutes getting it out and setting it up in a busy parking lot while also wrangling their willful, very curious child.
