You are wrong. Investing in human Trust and Relationships gives the best ROI. A person doing self-upvotes is never going to get the same Leverage and Return as the person investing into other humans. You can scale stuff when you invest in other humans. As you get access to more energy. You can not scale it by investing all into yourself. Coca-Cola spends 3 billion dollars per year in advertising. That is leverage. Same as best ROI leverage always will be invest in people with potential for growth.
