| One thing that can’t be scaled is “prime location” There will be locations that are more desirable than others, and even if you keep building houses where there’s space, the need to congregate in particular areas (such as for work) will result in particular locations being more desirable. And, it’s hard to increase the density of an area once the housing supply is already built out. So instead, that supply stays fixed, demand increases, and the price increases in turn. This actually made me think then that an accelerator for scalability could be: public transit into population centers that ensure areas with abundant space (and cheaper housing supply) can still easily access the areas that would otherwise be hugely expensive to live near I believe this was done near DC where the public transit buildout helped foster further housing development in those emerging areas. Not sure if other HCOL areas, e.g. CA Bay Area, have similar things going on for East Bay mobility / other cross-county transport |
There will of course be some places that are uniquely popular e.g. due to their geography or natural beauty. Humans tend to congregate around centres of economic activity, which means some places become popular. But creating sprawls of dormitory suburbs and efficiently piping everybody into the few places that are actually nice sounds terrible.
