Can you do it first, fastest, best, most inexpensively, and with massive volume? If so, you need a lot of followers. This model is repeatable and hard to defend.

Artists have succeeded because just one person decided to start collecting their work. That person’s passion brought a few more people. In reality a dozen collectors created a market.
Are you seeking everybody or just a few?
