A (good) idea very few will like.

Yeah, man but very few people like taxes but supporting a necessary infrastructure isn't a bad idea.

This is exactly what is bad about the idea. Everyone thinks taxes are allocated to specific funds rather than just tossed into a general slush fund the government can spend any which way they want like most taxes are. It seems like a good idea until you realize how it's being exploited/abused/mishandled by poor management and little to no oversight.

This OP's idea doesn't even really provide the SENSE of being a good idea from the start, how do you think it's going to end?

Also your comparison isn't really apt, taxes would be like what SE did to the market wards for selling items outside the designated ward. This OP's idea is more like the government coming to the local used car dealership and smashing all the cars up so people are motivated to buy from private sellers or buy new cars altogether.
