You're technically correct (the best kind of correct), but the TV license is very much like a tax as you're required to pay for it just for having equipment that can possibly receive broadcast TV.
this isn't true. you're required to pay for it if you watch live TV. you're perfectly allowed to have a TV or laptop or any other device that can pick up live TV
Sorry, I haven't checked the rules in a while. It used to be the case that owning a reception device required a license, but as you say, that's no longer the case.
