“If the state wants to ban this product, they should be buying back our inventory because we’ll have no use for it. It will be worthless, and thousands of fabricators will have the same situation with inventory and capital that’s sitting out there that they won’t get,” said Kolenski, who opposes a prohibition. “Plus we’ll have to buy the new product.”

Gotta love it... Hey we know we are killing our employees but if you want us to stop you gotta pay us for our trouble!

Here in Australia we already did..I have a friend with silicosis who was a stone mason

Of course, every business wanker out there before the ban whined it wasn't fair, but the fact it was dangerous was known for a very long time.

Business owners are knowingly putting everyone onsite at risk. And even if you can reduce the risk, the same owners are probably rushing their workers so they wouldn't have time onsite to be safe anyway

The risks have been known for a very long time, but they pretend it hasn't. They should have already chosen to shift away, not wait until laws are introduced to force them to

A very important detail:

maintaining that their products can be handled safely if the proper precautions are followed. But growing evidence shows that the dust generated when cutting or polishing artificial stone is so toxic that it can sicken people at sophisticated fabrication shops following Cal/OSHA’s current rules, which prohibit dry cutting of the material and require advanced respiratory protection.

Previously, the claim was that the workers were harmed because they weren't following safe handling practices. This indicates that's not (entirely) the case, hence the ban.
