When it becomes fine, it will be worth no more than someone coming to mow your lawn, and probably less than that.
EDIT: brace for the lawn mowing cartels led by ex human trafficking gangs. On a more serious note, there is so much criminality involved in that field precisely because it's illegal and lucrative. You remove that and you remove a lot of abuse.
It seems the main complain is that it brings the prices down due to competition from eastern europe.
