Yes but I'm not hiding behind a charade of economic jargon. Not that you are intending it to be a charade, but it will inevitably become one when translated into convoluted legislation.
It all becomes convoluted legislation.
You can easily block out large swathes of the economy as necessities (or otherwise precluded from discriminating) without delving into formulas at all. Food, clothing, medicine, lodging and housing, government services, and every utility provisioned either over a state provided/regulated common carrier, or any utility provided within a framework of regulated prices. Water and sewer/septic services might have to be put in separately to cover some special areas where there is no utility infrastructure and services are trucked in. I would throw in fuel as well. Drafted into legalese that could easily be down in less than two pages without a single formula.
Even without taking competition into consideration (meaning you have to sell your necessity even if a competitor sells the same thing next door), you are left deciding what items are actually necessities. If you just include something like gas, then you are preventing players in what amounts to an extremely competitive market from engaging in discrimination, even though in many places that would be a market most suitable for it (where the best argument for a market solution can be made). I guess the issue I face is that I see that a lot of individuals on this board provide a market justification for discrimination. There seems to be this constant belief that if a firm discriminates, patrons will simply go to a competitor or open a new firm, as if there is perfect mobility. Of course, this isn't the case. This leads me to formulate market-based solutions based on the efficiency of the market, as efficient markets appear to be the assumption made for the justification of discrimination (for many, anyway).
I don't think the list I just gave one paragraph ago would face much opposition at all. Granted expanding the list could be controversial (and maybe I forgot some things), but covering the basics is pretty straightforward.
The initial list is going to be controversial. And any subsequent modification will be hotly contested, and there will be modifications. And the moral argument for discrimination (personal choice) is eliminated in either of our scenarios.
That's not what is happening at all. There is nothing confiscatory about it because only things that are for sale are being demanded to be sold.
Your assumption here is that the items are for sale. The seller has the ultimate choice as to what is for sale. If the seller chooses to sell to black people, but not to white people, forcing them to sell to white people is eliminating the seller's choice. It may not be confiscatory as the seller is still getting money, but I never suggested it was. I was merely pointing out that it is still government intervention on an individual's freedom of choice.
Yes, but the intrusion is an act of making the market more closely resemble a competitive one. After all, most acts of discrimination based on protected categories are examples of irrational behavior (in the economic sense).
Maybe competitive, but not more free. It also doesn't contain the market mechanism of reward and punishment... punishing irrational actors, even if it is for their own benefit.
Yes, and that's a question I never want a legislator to try to answer. Some things always make for bad law. You might as well just go straight to a command economy once you have unilateral decrees of what constitutes a reasonable profit margin.
I'm not trying to confiscate profits or punish those who make them, merely using them as a metric to measure the efficiency of a particular market. If the market appears inefficient, enforce current anti-discrimination laws as the efficiency can be used as a proxy as to how much competition exists and how likely it is that the discriminated can create a new firm. That's hardly a command economy, at least not moreso than your scenario in which the government has decided what products are necessities and force private entities to sell those to anyone who can purchase them. Ultimately, you and I are favoring the same regulation, just differing as to who or how it will be applied.
