[Star Trek] They still do not have nonstick cookware?

In the episode "Mudd's Women" we are introduced to the miners on Rigel XII. We find that their cookware is very filthy because of the lack of water to use in cleaning. Eve suggests leaving the pans out in the open so the blowing winds and sand will scour them clean. 

But you would think by that time in the future they would have a revolutionary form of non stick cookware. The nonstick cookware of today does require proper care and maintenance, But surely by the 23rd century people would have foolproof nonstick cookware, that even roughneck miners could use. As Lithium crystal  (Yes, the term used in the episode)   miners it is implied that they are wealthy, so it would seem to be a good purchase to make.

There exist revolutionary food replicators so they don't even need to cook. But these miners are obviously going through tough times, because apparently they don't even have enough water to clean cookware, so they have downgraded to more primitive methods. And just because they are mining an expensive resource doesn't imply wealth, since they are presumibly many costs to living on an alien world and mining in general, and we don't know the details of Mudd's finances.
