Well, no. A business has an open invitation to the public. Your home presumably doesn't have that particular attached to it-unless it's also a hotel, in which case, no.
Is this analytic to the notion of a business, or is this by law? If the latter, then I've already called it into question. If the former,
then ex hypthesi, the business in question does
not have an open invitation to the public. It has an open invitation to the public
with the exception of gay people.
But that's rather the point. Arbitrarily denying a section of the public access is an injustice.
Why? You've already granted that a business is a private enterprise. A private enterprise carries with it the notions, as I mentioned to MM, of free association and private property. A has a right of possession over x. B wants x. A and B enter into a free association (a business contract) to exchange possession of x from A to B.
For you to claim that there is some injustice is for you to assert that there is something which is rightfully owed to B which A is denying to B by not entering into business contract. But for you to say this, it seems as though you have to deny A's 1. right over his possessions and 2. right of free association.
B It's denying them the right of access that you give others
Is this right of access voluntary or intrinsic? If the latter, I deny that such a right exists. Others generally have no right of access to my property. If the former, then I am entirely free to deny them said right of access. This right of access exists only because I've freely granted it, and therefore I can grant it and deny it to whomsoever I please.
Every business gets goods and services via the interstate. All businesses get benefits, utilize services paid for by general tax dollars.
How does this justify anything further than taxation? I buy things from amazon.com. This justifies my paying a state sales tax. But what I've purchased from amazon.com is mine. It belongs to me. I have a right of possession over it. You can't come up to me and say: "Hey, look, you got it via the interstate. So you have to let me buy it."
Likewise, you've already admitted: the business
gets good and services via the interstate. Therefore they belong to the business.
