Hi my fellow grandpa! It's nice to see I'm not the only one in this rewarding condition!

I just remembered something I saw in Germany about 15 years ago. There were special "graffiti boards" in train stations and other places. Sometimes you would even find markers, etc. So if you felt like it, you were free to write and draw whatever you wanted (except those 100+ "thought items" that are now forbidden in Germany).
Just like I gave up smoking as soon as it was legal for me, people gave up leaving their "foot prints" all over the cities. It just wasn't fun anymore doing things that now were legal. Many have this "I'm against it - whatever it is", and seeing that there are no more closed doors to open takes the wind right out of their sails.
So maybe sneering at those graffiti - telling them basically, "if you want to look like a little kid who has to paint on walls and everything, go ahead and make a fool of yourself" - might be the best and easiest solution. If you just laugh your... (hind end) off, laughing about those silly graffiti, guess for how long they'll continue doing that. And that kind of "law enforcement" won't cost a penny.
