I think in that statement the "extremely" carries way too much weight.

As it would imply price to be very high. Which then would mean that regular people would not have access. But they also widely used salt. So it could not have been extremely valuable as we understand. Or maybe gasoline is extremely valuable commodity now...

Yes, you can compare it with today's oil trade.

Salt production and trade have been restricted, usually state-owned monopoly. Cities with salt mines like Salzburg became extremely rich, like oil countries today.

Is gasoline valuable? Yes. Is affordable? Yes, but not for everyone. Same with salt back than.

> Is affordable? Yes, but not for everyone. Same with salt back than.

That isn't possible; someone who can't afford salt dies. It's like claiming that water "isn't affordable for everyone". It is, and it must be, because people who can't afford it also can't exist.
