For the same reason we pay for a lot of things we may not ever use. It was put there for there for everyone based on a need for some people. Schools and roads are good examples. Some folks never have kids but they pay for schools. People pay for road taxes but they don't drive on most of them.
The idea is that we all pay for things that are deemed for the majority or the greater good. You may not need (or want) them now but they are there if and when you need them.
