I mean I paid for it like I would anything else I wanted. They charge a tax at checkout. So if I buy a house and pay the whole thing off, why do I still have to pay taxes on said house when I paid the whole agreed on price in full? It would be like me buying a six pack of beer I pay for it and tax at checkout. But then timely I have to keep paying taxes on the beer even though paid in full?
That pack of beer doesn’t require an entire infrastucture of services to maintain… when you buy a house (really the land) you are buying a stake in the community, a community that requires upkeep and you are agreeing to pay your share of the upkeep… think local law enforcement, fire departments, emergency medical services, infrastructure maintenance (sewer/water/roads), and I think the biggest one, local education.
I was curious, so I looked up a couple large cities. New york has a long budget document that really lacks charts, but talks a lot about schools. Somebody made this visualizer (which lacks pie charts! Why?!) for LA. Montreal has some reasonable pie charts for where their tax dollars go.
