Not really, no.
In some remote places yes, and there are a small number of ultra expensive mansions that sit as 5th+ properties but by and large there is not enough housing for everyone.
The vacant houses additionally include ones that are condemned, ones that have been sold but haven't been moved into yet, and ones that have been moved out of, are on market, but haven't sold.
Realistically you need about 5% of houses to be vacant at any given time to have enough stock open for people to just move around like normal. Anything less than that is a shortage.
Many American cities are sitting below 2% vacancy - which is an extreme shortage. NYC sits at 1.41%.
There are no answers to the homelessness crisis besides building housing. A lot of it.
That's not a printer hobby then, it's just a cheaper but more time intensive way to get to a printing hobby.
If you enjoyed the process all the better.
Not everyone has the cash to shell out for a Prusa or Bambu - getting an ender and upgrading it can represent 50+ hours of work but $400+ in savings.
