You’re tired of skateboarders on your street, though there are a lot fewer of them these days than there used to be. Your city/housing association won’t build a barrier at the end of the block. A lot of people don’t think the skateboarders are as big a problem, or even a problem at all…
But this is an emergency! (Even though the numbers are already declining.) So you take your neighbors’ money and put spikes across the street and their yard. Nothing on wheels is going to get through!
Meanwhile, the skateboarders keep walking in on the sidewalks, carrying their skateboards, like they’ve always done.
You’ve misappropriated funds, violated your neighbors’ property rights, blocked traffic…and yet you haven’t actually addressed how the skateboarders are showing up in the first place.
