Yes, but the monopoly seller has already demonstrated that they will operate at a loss until their competitors go out of business, which is a pretty big deterrent to any new market entrants. They've also demonstrated that no one will be making any money until either the monopolist or the new entrant is out of business, so who would actually launch a new business in that environment?

Even Amazon had to eventually find its way to profitability.
