Roads can't easily bill for usage and a vast majority of people relies on them, thus the easiest & most efficient way is to make everyone pay for them through taxes, though you do pay more if you own a car via extra taxes on car registrations & fuel. Hospitals can technically be billed per-use but the US is a real life example of why the system doesn't work in practice. You could also argue it's a necessity for life and everyone should have the right to medical treatment. Armed forces? We're gonna disagree big time on that one but that would be off-topic. But the BBC? It's something that's not necessary to life, affordable and trivial technical solutions exist to make it paid per-use (pay TV existed for decades and streaming platforms have solved the "online paid subscription TV" problem) instead of threatening people into paying and producing a significant amount of paper waste as a side-effect.
