If, for the good of the country, the president has to sign an executive order abrogating the right of free association for a private business then that business should be nationalized because obv pursuing the profit incentive is deleterious to the health of the country.

Also, maybe 20 years ago, about 15% of the US public did not have a bank account at all, for various reasons, but including people who were too big of a PITA for banks to deal with. Will this sort of EO force businesses to work with people they don't want to?

It's because they didn't want to work with Trump, it's not about anyone else.

That raises another question. Does this EO mean that banks have to work with someone who's obviously criming?
