If you write a book and there isn't sufficient demand for it, then they will because you will earn nothing and be out the printing costs while they paid nothing (and get nothing).
People buy your book because they value it more highly than the money... so they are getting something out of it. Whether what they get out of it is more than what you get out of it is a function of demand, price elasticity, competitive options, etc. You should want your readers to get more out of it than you do... because they're a lot more likely to spread the word that way.
Like it or not, it's a DPOS blockchain. That means the chain literally belongs to the stakeholders (SP holders) in proportion to their holding. Convinced the owners that what you're doing on their chain is worth their support, and you will do just fine. Convince the owners that what you're doing devalues their chain and you will be obliterated.
The value of a vote belongs to the curator (it is inflation on their stake - and they control the distribution) by default. Rewarding the curators isn't to pay them for finding your content and putting a vote on them. It's to encourage them to vote your content by making it relatively cheaper to vote for your content than their own. And if it's cheaper, then it's more likely that they will pay for it with their votes.
I would rather have 1000 people send me 3 cents each than have one person send me $3, and if selling my content more cheaply (making voting on it cheaper relative to self-voting) makes a lot more people vote on it, then it's worth it.
On the other hand, if you churn out shit because you think you need to produce 3x as much to offset your 'lost' entitlement, you are going to get a lot fewer votes (because even 0.001 is too much for shit) and when you do they're more likely to be off-set by people that realize 0.001 is still too much for your shit and don't want that coming out of their inflation - even though the vote value belongs to the curator, it's actually the consensus influence that belongs to the curator, and somebody else may use their consensus influence to remove you from receiving rewards completely.
