1. I think so, but things as we see them today would change a lot, and it would be more about buying STEEM, power up and then getting the most out of it by upvoting yourself at 100% every fucking day

2. There it needs to be an strong incentive for that person, not just money, but reputation, personal branding, advertising, etc

Maybe whoever invests his money is not a person, but a foundation, for example, or a company.

There has to be a business model for the investor that goes beyond proof of brain or receives rewards for creating content or curating

I'll think more answers during the day, now I'm on my way to work.
