A eureka moment is realizing that customers interests are actually aligned with businesses being profitable. If the business provides the customer with something they want - and they usually do, if the customer is willing to pay them money at all - then it is in their best interest for the business to continue operating, which means it is in their interest for the business to have a profitable business model. This is part of why you see a bias toward big companies winning sales, even at a higher price point: there is less risk that they will go out of business and leave you in a lurch. It isn't actually in the customers interest for a business to barely or not at all be able to make ends meet, which is what your proposed business model has often led to.
