I must disagree. In fact it has been proven as practical by several development projects that were funded that way (when the value of Steem was higher). It isn't exactly a development project, but @burnpost raised well over $100K using daily campaign posts (again when the value was higher).
It is all about where stakeholders want the rewards to go (which in turn depends on what they are convinced is going to increase the value of their investment), regardless of the mechanism.
Fine, if that is your opinion.
I feel that with lack of leadership from steemit other processes are required.
To be clear, I'm not opposed to a worker system as I've recently stated elsewhere. I thought one should have been built starting with HF16 in 2016. But I don't think it is needed and I also believe that a lot of care needs to go into designing it (including being willing to make a number of revisions for continuous improvement if necessary, not something that has been a strong point around here) to end up with results that are significantly different from the poorly-performing stakeholder-voted reward system we already have.
Also, how would such a thing get built? Steemit seems unlikely to build it. Maybe blocktrades could do it but they would want to be paid. So we use the existing system to pay them or ???
