Hi @venturefounder,
I am a bit late to comment here it seems. I am strongly aligned with @MarcZeller and @fig. The business is still very early and there is a lot of growth ahead. With strong cash flow the business should be re-investing in itself to promote growth. The BGD, Aave Grants DAO and Gauntlet initiatives are great examples of how the DAO should be pursuing growth in my opinion.
Buying back equity now or even paying a dividend would be a signal the business lacks alternative investments for these funds. A company that pays a dividend to me signals it lacks the ability to invest this capital and earn a higher return on behalf of investors / token holders. More generally the DAO is in a place of rewarding those that help grow the ecosystem which involves distributing equity plus stables.
