collateral and incentives are seperate from superpeers
though you must be running a superpeer to get the reward, its basically just saying those with 10k VNL and a superpeer get to tax the miners.
For what purpose? They must have an influence, otherwise they are pointless.
pointless?? seriously? you think having more fully working nodes is pointless? ask Bitcoin supporters if they would like to have more fully operational nodes or not
