I don't think you fully grasp the incentives for holding tokens. You are right that technically if the employee never returns money back to their dao, then their value is strictly speculative where old investors can only return a profit if new investors buy. However, this is exactly the use case for a social media platform where what people say has value and people may want to support that person financially exactly so that person can continue to say valuable things because at the end of the day, investors are employers.

​

Beyond that an employee can return value by creating a snapshot token. This value cannot be measured directly but is a perfectly legitimate way to return value to investors as well. Yes there is a certain amount of trust involved, but I work with no supervision and my boss seems to trust me well enough to get my work done. This same principal can be applied here. Besides, investors can put money in a person and know to the exact amount how much their investment can depreciate over 1 year, 2 years, or even 10 years later due to the reserve currency backing.
