Have you spent much time here lately?? This seems to be looking at Hive as being the same as Steem 4 years ago - it isn't.
Click the link and have a look at the transactions:

SL = Splinterlands
Splinterlands is worth about 500M dollars currently - would it be worth as much if they had to pay for transactions?
Which interface are you using? hive.blog?
Try peakd.
Key management? Try Keychain.
Censorship resistance? Quoting Justin Sun events doesn't work, as the last hardfork made that impossible - plus, the mining stake he bought in STEEM from Ned, is now in a DAO and funds development of applications. Plenty of people can run nodes - You can run a node. 
Most of the voting stake isn't in curation guilds, it is just that they can make push individual posts up. The curation here isn't really centralized at all - except by stake.
Also, you seem to make the assumption that the people who have worked hard on Hive, only hold HIVE - that is not the case. Looking at a Hive wallet for whether a person has been financially successful, is very much judging a book by its cover. For example, there are dozens of Splinterlands millionaires with very little HIVE, but without Hive, they wouldn't be millionaires.
I think you are looking far too narrowly at this space. It was never meant to be only a blogging platform - it is an application ecosystem.
