Orwellian naming as usual.
Marketplace Fairness is not forcing me to buy from localized monopoly chains by penalizing me for taking advantage of "fair market" capitalism to force companies to compete, and reward the better one. Of course, NAFTA is okay and even subsidized and corporations won't be "hit", this is just another means to attach costs to making choices to prevent choices from being made. Using prices, wages and taxes the poor can be ensured to be poor forever.
This started with the laws aimed at buying out of state/country cigarettes/alcohol. As some regions began using "punishment taxes" to regulate the impact of "bad habits" on the poor only, the poor responded by going to other places, using competition in the free market. Does this value only apply to corporations now? If these taxes were designed to have equal impact, the "punishment tax", or as Indiana calls it, the "Sin Tax" would scale with income to ensure that rich people are "just as restricted" from smoking/drinking as poor people.
To keep people down, laws were made and proposed ever since to penalize everything, including choice. If my locality only has monopoly chains I don't want to buy from and way overpriced crappy mom-and-pop stores who are just as bad, yet 2 miles to my east in Ohio, I can instead buy from a different seller, why shouldn't I? Punishing me for that reduces the choices I can make.
If my city decides to impose taxes against a product, and I can avoid the tax the next town over, then I should be allowed to make a choice and not be punished for it. If my town makes a law against R-Rated Video Games, the government shouldn't be able to stop Steam from selling me a game with adult content, and they shouldn't be allowed to punish me for using steam rather than going to EB Games, the only place in town (which I won't shop at).
One precedent this could lead to is city/county taxes being added to the penalties, so that if you go to the next town over to eat at a restaurant, get some gas and watch a movie, you have to pay city and county taxes. No surprise that all of these laws target citizen commerce and not corporate commerce, regulate humans but not the market.
I wish I were a corporation, because I would have more rights than I do as a human.
