A lot of things work this way. The government is quite literally taxing some of your income and using it to check if you're doing anything wrong. When a cop is checking your car for parking violations, they're using some of your taxpayer dollars to see if you're doing something wrong. You don't benefit at all from your car getting checked. But you probably benefit from everyone else's cars being checked, which is why we have this system. Or similarly, you don't benefit from airport security searching your luggage. It's a waste of your time and invasion of your privacy if you don't have anything forbidden and even worse for you if you do have something forbidden. But you help pay for airport security anyway because it might benefit you when they search other people's luggage. You don't benefit at all from having your photos scanned. But you (or someone else) might benefit from everyone else's photos being scanned (if it helps catch child abusers or rescue abused children). It's just a question of whether you think the benefit is worth the cost.
