How are development projects and marketing initiatives not going to be 'centralized'? Do you think it makes sense to pay out a few dollars to each of hundreds or thousands of different accounts such that no one is being paid enough to actually do anything?
I think it's fair to criticize specific proposals as being overpriced, ineffective, or generally a waste of money, and that's an important debate. But I don't think "centralized" really makes sense as a criticism to funding work projects at our current scale of hundreds of dollars per day. To be distributed more widely would make each payout utterly meaningless and clearly ineffective.
