(13,598 posts)Estate agents and auctioneers often fail to predict what value things will or won't sell at. If it can be done reliably, why aren't they doing it, and what makes you think the government would/could do so more accurately (without massive expenditure)?
Yes, in an ideal world, taxing possessions would probably make more sense than taxing transactions. But the great virtue of taxing transactions is that you can see precisely how much benefit someone got out of them; if you tax possessions then you risk screwing people over when they turn out to be unable to sell their house, say, for as much as the taxman valued it at.
You assert that that won't happen, and that the taxman will always be able to predict how much things will sell for. But I'm afraid that I think the evidence suggests otherwise.
