I find two very big problems to what you just said.
Steemit posts, basically, art, has no intrinsic value to it, and unlike art, you can't buy a internet post (i mean, you can, but ... : https://www.recode.net/2014/8/2/11629454/this-post-is-art-framed-4chan-post-sells-for-90900-on-ebay) . And i think that you mentioning communism, which is famed to "only work in the books" proves that there should be not too much trust to be put in steemit (as it is) . I mean, one of those days communism may work and wouldn't it be great, but at the moment we are stuck in a "So we try communism again and it fails, but it doesn't matter it was not real communism anyway" .
I don't like debating politics, convincing anyone it's so difficult that its funnier to stick with dirtbag centrism just to fish a reaction.
Literally all i would need to be able to trust steemit would be ads partnerships . Even if they can be disabled, and the possibility of promoting posts by burning steem, (no selling, no increase of reward, that steem is gone forever from the network)
