PayPal limiting acount access to everyone who sold a PS3 or Wii

I never figured out how this illegal business called "paypal" been allowed to operate for so long. It can randomly and arbitrarily deny its customer's access to their money indefinitely without recourse. It can utilize the monopoly of eBay and gain an unfair advantage when competing with other payment services. It has NO customer service, the paypal CSR knows nothing and can do nothing. What can be done to stop the "paypal/ebay" evil empire?
