First, you're making a significant and relatively ignorant leap that the ones "stealing" are interested in paying for the service at all. If they're cut off, they're very likely not going to go sign up for and pay for the service. I'll just say it again- the price and the market demand are not aligned, very clearly. These people aren't drug addicts trying to keep their fix.
Second, maybe in the short term people pay more than their "fair" share, which itself is meaningless babble because you decided it was "fair" when you kept paying it. When it isn't "fair" you'll stop paying it. But anyways, there are two ways the second bolded point is easily proven false. One, when the price gets too high (is unfair for everyone, using your words) nobody is paying for it so nobody is "paying more than their fair share" because the price/cost is zero. Two, as with the famous tax example and multiple studies and real life examples (not just in taxes but in hotels, flights, music service subscriptions, video game services, etc.), when the price actually retracts to somewhere that people deem reasonable and aligned with the value, they're almost always more than willing to pay. It's why the Congressional Budget Office frequently tells politicians that when tax rates reduce, revenues actually increase- people don't dodge anymore. Eventually someone catches on and things go the right direction. Another example- music pirating is way down because now people can access the music they want to listen to via services like Spotify that align with the value they're willing to pay. This is beautiful market economics at work!
You seem to be letting some preconceived notion of "entitlement" cloud reality here.
