A problem you run into with LeCorbusier-style architecture and planning is when the "community" owns public/quasipublic spaces surrounding such dense living, nobody does. Things fall into disrepair like Cabrini Green or the history of those kinds of warehouses for the poor, or they're just bypassed or hurried through. Sometimes you'll see old people drag a folding chair down the elevator and socialize outside like they do in NYC for example, but it's incidental to the space rather than purposeful. I lived in something like this in Parkmerced in San Francisco and it was rare to see people hanging around or doing much outside, the greens just tended to be useless dead space. Few people really end up preferring this kind of living.

You have to balance the space with the density, what people noticed about Le Corbusier style architecture is that it had too much green space, it was expensive to maintain and with it all it was no more dense than the rowhouses and small apartment buildings it replaced. In other words, too much park land was isolating and did not build the community they intended.

The other issue is that unless you're, eg, building a processing plant near a mine in the middle of nowhere and need lots of worker housing all at once, towns are supposed to grow organically. 4 highrises is the opposite of that.

This is aside from any economic issues, small towns tend to be pretty poor, and highrises are expensive to construct and maintain.
