The cheap $20 versions of those things have awful wheels and are pretty much unusable anywhere that has weather or uneven pavement. I had one and never used it. But then I started using a $500 baby stroller. Of course at first I only did it including a baby, but once the baby got too big for the stroller I kept using the stroller for groceries because it worked well. Eventually I replaced the baby stroller with a "garden wagon". https://www.google.com/search?q=garden+wagon
in any sufficiently developed place those shopping carts are good enough. my grandmother had one with three wheels on each side connected to a central axis allowing her to pull it up on stairs with much less effort. as a kid i found that fascinating.
Mine sucked at curbs. It worked, so probably "good enough". It was just annoying and I preferred to just carry my groceries before the baby and their stroller arrived. But if your grandma was handling stairs with hers, curbs likely wouldn't have been an issue.
They are nice to have in general, not necessarily for daily use, or shopping. Just for when something large and heavy comes, or has to go. Like fridges, washing machines, ovens, or laaarge screens :-) Can be stowed away easily for being ready just in case.
Makes sense. Have to get past looking homeless pushing them as people who do push those in my areas are homeless. Its just a mindset shift though not insurmountable.
