I highly disagree with your comment. We have learned over time that we can't trust a centralized entity like steemit to take care of everything. Especially when there is no clear line as of where community dev should start and when steemit inc dev should stop. A simple example is steemit.com. This website is terribly outdated and is supposed to be the flagship of our blockchain. Or what about communities or smts ? Or marketing ? Also having a centralized entity means that we all sit and wait while steemit inc does the lifting because they have the funds. If the company has a huge crisis (like if they laid off 70% of their employees). And we know that they will be delaying smts to reduce costs what do we do ? Well this is where we as the community will be able to pick up the slack thanks to the proposal system.
Right now the current situation is "do things and get high up enough in the witnesses to get paid for it" but this is flawed as witnesses should be elected on trust and their capacity to keep the network secure not side projects. The worker system would allow us to clearly separate things.
