Every time you turn around, governments are attempting to enact some new law to take over a person's RESPONSIBILITIES. Baltimore County is now considering a bill to regulate flyers left at houses. The proposal is replete with a "do not leave" registry. The county's most recent foray into that area was a law forbidding "bandit signs," those you find stuck in the ground at every intersection, especially on weekends. Since the enactment of that law there has been an exponential increase in the number of these signs. It's obvious that this kind of lawmaking does not work, just as preventing law-abiding citizens from buying and owning firearms does not keep thugs from obtaining and misusing them.
Being an adult consists of picking up everyone else's messes. Whether it's your child's, you spouse's or your neighbor's.
And if you think picking up trash off the lawn is unpleasant, wait until you find yourself having to clean up the intimate messes of an chronically ailing spouse or an elderly, incontinent relative. Particularly one of your parents.
Grown-ups just suck it up and do this stuff. To expect the government to take the responsibility is to invite them to take over your life in any number of other ways, often unforseeable and almost always undesirable.
If you were my neighbor and didn't want this responsibility, I would happily clean up the stuff thrown on your front lawn, rather than empower the county government to pass another law.
