what would you get rid of? I mean, let's play pretend!

When as adults do we get to do this??? Let's pretend that you can have your own perfect world, and in it, you can get rid of whatever you want, and there would be no repercussions. Example, if you say you would get rid of traffic lights, no one can come back and say, but you'll have a bunch of accidents! This is just pretend, and it's all our own little perfect world!!! (I'm having an I Wish I Was A Kid day, lol)
In my perfect world, I would get rid of 18-wheelers, parking meters, and railroad crossings, blue hair dye, gnats, and ants.
What would you get rid of in your perfect world?
