No it’s still a very small number. For comparison that’s about the same amount as Germany, a nation less than 1/3 the size. The US simply does not have a serious homeless issue and it definitely isn’t “bad for a developed nation.”
Yes when it’s that small of a percentage it can be argued that homelessness isn’t the problem. Mental health and drug addiction is but those have different solutions and namely ones that can’t be argued to have a left economics solution.
