It is absolutely the correct way to track the value of assets.

Whether it makes sense for a particular person is subjective. Some people care, some don't. Clearly you don't. Nothing wrong with not caring so I don't say that negativelty. You do you, as they say. But, the fact that you don't care does not alter reality nor invalidate the math.

> Can you at least agree that a car doesn't lose any value just by driving it off the forecourt?

Of course it does lose value when you sign the purchase papers, this is not debatable. Not a matter of opinion.

You can trivially prove this if you wanted to. Go buy a new car from the dealer, drive it a mile or less to the nearest parking lot and now try to sell that car for the same amount you paid. You will never be able to find a buyer. If you want to sell that car you will have to lower the price to get any takers. So there, you lost money.

Probably not worth trying to continue to respond factually in that case.
