Ubitquin,
2. I urge you to take a remedial reading course. I pointed out that you distorted the SA by truncating the halacha. It explicitly says that only foods necessary for life have a profit limit. I pointed out that today everything has substitutes and many people do not eat bread during weekdays. Some people never drink wine, which is also on the SA’s list. I also pointed out that free competition would keep prices down. The officers to whom the SA refers could be prosecutors who fight coercive monopolies.
3. Be pious with your own money, not with others’. When Avraham Avinu refused to take even a shoelace he also insisted that his soldiers receive their shares.
4. I do not believe that there is a view to favor unrestricted competition in America. Look at all the rent-seeking licensing laws. LA even has one for flower arrangers (it is being fought in the courts).
