Did you miss the part about it being calculated in the cart? That’s after you’ve made the decision to purchase, a decision which presumably included the price. I would refuse to give every vendor my address just to see a price.
How does it work now? If you don't give your address, but the price depends on your address, how does the store know how much to charge you? If you don't have to give your ID then surely you just say you're from the lowest tax location?
It only really matters where the goods are delivered.
I don’t want to give my address to see the price. After I’ve decided to buy the thing, I’m okay disclosing who I am. But simply to see the price?
Also, if I’m a retailer and people are giving me their address before I price them, on what planet am I not going to use that to help me price discriminate?
Taxes don't change every street.
Ha. Oh boy. I remember when an engineer at a POS system start-up said something similar. It's like when someone decides they're going to roll their own time zone calculation.
In case you're curious, yes, two people in the same city can be in different counties, different school districts, different water boards, et cetera. Each of those typically has taxing authority. And this is before we get into crap like urban enterprise zones [1].

Also, Apple Park is in Cupertino the city but not the school district.
I've seen cases where a neighborhood was split. Two near-identical houses, but one had less than half the property tax of the one next to it.
I live near a place called Westlake Village that straddles the LA County/Ventura County line. In LA County, Westlake Village is a city. In Ventura County, Westlake Village is a neighborhood within Thousand Oaks, and it has a different tax rate. But both mailing addresses use Westlake Village as the city.
Similarly, I have friends that live in Newbury Park, and that's what is on his mailing address. But Newbury Park is just a neighborhood within Thousand Oaks.
