I’d argue that the taxes are a separate cost, which would be paid separately rather than being included in the “purchase price” you’re using your dollar to offset. In OP’s example, the TV requires electricity to run, but the cost of that electricity is (presumably) not bundled into the purchase price. Just like maintenance on the house would not be included up front, as it’s a separate, additional cost.
If you reject that, I’d argue that the land will exist well beyond the fall of civilization, and at some point, there won’t be a government to tax it. It will, however, still exist. If the land costs $400,000, and taxes are $10k / year, and we expect Earth to last about 8 billion years, and we expect government taxing the land to exist for, say, generously, 10,000 of those years, that’s only a net cost of $0.0125 per year. In this case, the land itself only costs $0.00005 per year, so you could buy quite a lot of things for your dollar, in fact.
If you teleport to it and back, that’s way more valuable than anything you’d actually be buying. I’d just use it for that purpose exclusively. Choose a plot of land to “buy” that’s calculated to a specific timeframe, matching how long I wanted to be there. “I want 200 square feet in Norway.” Day trip to Norway, let’s go!
