I do think the simple fact of offering hyper-dense communities (especially in cities that lack them otherwise, like many midwestern cities, say) makes any downtown attractive as a living option to a certain group of people who want the "15 minute city" experience. Doing so tends to transform downtowns into actual communities as well, as opposed to places with many low quality vendors that cater to duller, less personable 9-to-5 routines.

And then of course there are knock-on effects to placing people like that (typically young professionals and artists) together like that to rub shoulders, talk about ideas, start businesses etc...
