The bandwidth requirements for running an Ethereum node will not work for many home internet connection types. For Comcast, at least, with a 1.2TB/mo limit, the node will run you afoul of The Man within a week or two.
It would make much more sense if a tiny trickle of Eth were dolled out to the validators... they are just as necessary as the miners/stakers/etc. Take some fixed percent of the mining reward, divide evenly among all validators. Done... I mean in principle if the function is necessary, it should be incentivised.
I did mean the full nodes they are promoting the benefits of running on the linked posts. Must have gotten words mixed up when thinking about validate rewards and not noticed.
