I don't disagree that the credit card companies are scumbags and they need to be held accountable.
But Jersh is never going to force the banks to provide him a service because they're not obligated to.
You know how some Japanese restaurants will refuse to serve foreigners because they had a bad history with them? (Think Logan Paul and Johnny Somali). It's the same with banks where the banks have a right to refuse service to anyone. If you were to go to Japan, you may see a "No Foreigners Allowed" sign on the front window of some restaurants and retail stores because those businesses had a bad history dealing with tourists that don't know how to behave themselves (making the customers unconformable, engaging in religious solicitation with the other patrons when it was not wanted, engaging in business solicitation when it was not wanted, being loud and obnoxious, and other behaviors that forces said Japanese owners to kick out the gajins that fail to read the room).
In the case of Jersh, he simply lack the people skills and lacks foresight to not piss off any bank he does business with.
I hate to use the "It's a private company, they can do what they want" argument but generally speaking no one is really entitled to be provided private services because being provided a private service is a privilege and not a right (much like how driving is a privilege and checking out library books is also a privilege).
The American Constitution guarantees free travel around the country for its citizens and legal residents (freedom of movement is guaranteed in the American Constitution) but it doesn't guarantee a right to a specific form of traveling (such as driving which is seen as a privilege) and you're still free to use other modes of transportation to get to one place to another if you can't drive (such as the bus, airplane, taxi, Uber, the train, streetcar, the subway, a horse, a bicycle, your friend offering you a ride, use your two legs and feet, you really don't need a car to get from point A to point B in America). It's also like how if you are accused of a crime, you have a right to an attorney (a court will provide one for you if you can't afford an attorney) but you don't have a right to a specific attorney; beggars can't be choosers.
If you run a business and some obnoxious fuck makes a scene that scares away your customers, you're going to kick the obnoxious fuck out from your business because they are bad for your business.
Why did Chris-Chan found himself getting banned from the various retail stores in his local area? Because he's a retard that makes other customers uncomfortable and his bad behavior is bad for business (it's why Micheal Snyder kicked out CWC from The Game Place permanently).
In Jersh's case, the banks see Kiwi Farms as a high risk business that isn't worth the effort because he will scare away banking customers and potentially give the banks a lot of bad press. So the banks have every right to physically remove Jersh from their services and refuse offering any of their services to him much like how a restaurant owner in Japan has the right to kick out annoying gajins from their property.
I don't even know why Jersh calls himself a right-winger when his ideas seem more closer to lefty socialism than it is to actual right-wing thought as far as economics go.
