And this will be paid for by what means?
I am trying to find someone to clean up my weed patch and I know it will cost several hundred dollars to hire someone. What if I can't afford to hire someone? Will you do it for free? Will the government do it? If the government does it, who pays for it?
I wish my yard was the envy of the neighborhood but time, money and decrepitude make that impossible. It is very possible that some of those other yards fall into the same category. Taking their yard away from them hardly seems fair but how should it be handled? And, again, there are people who are mentally ill and don't see their treasures as mess. How do you deal with them?
Life, sadly, is so much more complicated than we wish it to be.
