Political correctness, occupational regulation and the 1st Amendment

What is occupational and industry regulation for?

Isn't it supposed to be protection of consumers from bad products and dishonest merchants or service providers?

Then, what is the legality of prohibition for a farmer to sell his perfectly good apples to consumers in 2017 because he refused to provide his orchard as a location for a wedding of a gay couple in 2014?

What did that do to the quality of his apples?

And, what good does ruining a business of an apple grower do to consumers of apples?

Wouldn't there be less apples, at higher prices?

Not to mention that the government may not regulate based on somebody's political views.

And, the orchard grower did not discriminate as to who is or is not to buy his apples.

So, the politically correct assault of the government on the 1st Amendment continues.  The stupid way.  And at the expense of consumers - as always.
