You seem to be giving Greg to much credit. It was Satoshi's idea to make the currency deflationary (eventually) by rolling from block reward to transaction fees as a means of funding the operational infrastructure.
...which would come into play several decades later. Do you deny Greg has advocated for making blocksize a scarce resource and intentionally creating a fee market now?
As for 'corporate', I cannot think of anything more so than then Bitcoin bloating to the extend that only a handful of large corp/gov entities are able to operate it efficiently and profitably. Such a scenerio is necessary for coin blacklisting/whitelisting and that seems to have been the primary objective of those who got the bloatchain idea rolling.
I think we agree that coin blacklisting/whitelisting would be bad. But it seems to me that this would be just as likely (if not more likely) to occur due to institutional control of main chain transactions (the inevitable result of small blockism) versus institutional support of full nodes.
If you disagree, I would at least listen to your argument.
As I see it, a healthy number of full nodes are good, but miners control what goes into blocks and mining is already commoditized and commercialized. I don't see a problem with that. But I do see a problem with institutions becoming gatekeepers of what and how transactions flow through the network in ways that are unknown and unpredictable.
