Part of me wonders if he saw this image online and got that idea from here.
I would've thought that he was talking about Walmart, which does a lot of business in food (but never good in the perimeter departments) and (traditionally) sold firearms as part of their sporting goods department. (They're on opposite sides of the store).
Non-Americans/poors/retards (Null being one) think that this is what all/most American supermarkets are like.
Toronto's PATH underground walkway/shopping center is suffering from the same thing (vacancies) and I'm willing to bet the problem in both cases is exorbitant rent.
Toronto was hit pretty hard due to COVID and I believe that before COVID, at least the Eatons Centre was open 24/7, an established agreement because the construction of the mall closed off several streets (which helps put clips like
this, from 2010, in context).
I suspect that most of the "underground concourses" have suffered greatly post-2020 and PATH is no exception.
I did not like living in the big city, but one upside to endless stretches of strip malls like in LA or Phoenix is that the grid layout makes it easy to find places. In some old-timey European-y place, it can be like a cobweb of roads all over the place. While the latter may look much better, it sure can make finding stuff a lot harder. Assuming you're not using a "smartphone" or one of those GPS things, an address in a grid layout can be easily reached just by writing down the intersection it is closest to, while a course to an address in a cobweb layout would have to be plotted with a "stick map" (perhaps with landmarks indicated). And good luck planning a bus trip in a cobweb layout.
The "cobweb" city layout is generally a holdover from medieval times, and it wasn't even rebuilt after World War II because the roads were the things that would've changed the least.
The funny thing about street grids is if you look at something like New York or New Orleans they're built on a grid system. For Europeans crowing about how awful the grid system is their ancestors would've built their cities on a grid system if they were offered the chance.
1) the goddamn stench. Main street and the surrounding roads had an inescapable stench of horse manure. The only methods to get away were to duck into the air-conditioned stores or head a few yards to the nearby rock beach on one side of town. The only full reprieve was when I hiked a good half a mile away to the nearby nature preserve area. Having grown up around car fumes and livestock smells, livestock manure still smells worse.
2) It was a very high-trust area. I didn't see any vagrants or hooligans looking for a handout or causing trouble. I found myself actually lowering my guard in a tourist zone, which I was taught from a young age to never do. It probably helps it costs a good bit to get on the ferry and that hardly anyone talks about the island except locals or people that lived in Michigan at some point.
3) The actual residents were very racially homogenous. I think I counted about two or three people of any color working the stores or stocking (that I saw, at least). Even the tourists were mostly white.
4) A big part of why it was pleasant to walk around in was because it was a very pleasant day (mid-80s, low humidity, hardly a cloud in the sky, which is nice for early August). I would probably have been absolutely miserable if I had to get around on a bike when it was raining or there were two feet of snow on the ground.
5) Mackinac is pretty small for an island. My family and I were on it a few hours and we were able to walk everywhere easily. The only thing we didn't do was visit the huge hotel.
The logistics were probably another reason. Things are probably more expensive there due to the touristy economy but there aren't easy loading docks.
I don't think your observations will be noticed by Redditors because it's basically the same issues of college campuses. They often talk about "well, college campuses are walkable, what if the whole city was like that" because you run into the same issues:
- High-trust/homogeneous area (while colleges aren't necessarily all white, they tend to have like-minded people around, well-educated young people that for the most part speak the same language you do)
- Relatively small and needs a bigger "support center" that cannot be converted to a walkable district
- Highly seasonal
