Well if you want a serious answer, a) because why look internationally when you can first draw from internal solutions, not educated on what the article discusses (i went to the comments first), before trying to examine policy in a different culture on the other side of the planet, check and see maybe what your neighbor is doing first, and b) Europe, on a per captia basis, doesnt appear to be doing much better than Utah in terms of homelessness. A preliminary google search shows Utah has a homlessness rate of 9.8 per 10,000 people, and similar rates in Europe appear to be 22 (France), 23 (Netherlands), 41 (Germany), 11 (Denmark), 12 (Ireland), 33 (Sweden), 10 (Finland), etc. Doesn't look like, generally speaking Europe, has a better solved homelessness problem than Utah specifically. Doesn't answer why Florida which has a 13 per 10,000, but probably see point of neighbor being easier to work with than someone an ocean over. The outliers to this with exceptionally low homelessness numbers in Europe appear to be (again, just on preliminary seaching),Spain (5), Latvia (3), and Croatia (1). Not saying this to nessicarily defend Utah or to shit on Europe, but something to consider.
