Yeah that's true. But from a UX perspective there are ways to make this less opaque. Perhaps a call to action at the top of the listing with an entry box to enter the Zip Code so an approximate final price can be calculated.
Any good UX designer can come up with a solution for this in a couple of hours or less. There's just no motivation to make it happen because this obfuscation of data is particularly optimized and useful for the sellers.
