You can do that when nobody else is allowed to start selling your product, sure. There&#x27;s an important difference between being the only vendor in a market because nobody else has bothered, and being the only vendor in a market because nobody else is allowed to compete with you. In the second case, we always see prices &quot;raised to the moon&quot;. But it can&#x27;t be usefully compared with the first case; potential entrants may not exist yet, but they&#x27;re still a constraint on the prices existing vendors can charge.
