You are right in saying everyone can choose what they want to use. But telling people "if you don't like it you can go somewhere else" is a very unwise policy for such a small project as Steem. Its still in its infancy and its survival is not even close to being assured, so it should hand-hold its userbase.
Also, DPOS does not have to go to the extreme Steem is taking it. For example, the HoboDAO intends on adding a Loom Network DPOS website to its long-term roadmap, but one's total amount of HBO will not give you wildly large votes over anyone else. The reason for this is that whales are a form of centralization and thus a security risk. Our aim is decentralized journalism, while whales with equal vote authority to stake get to have more opinion than the overall community, which makes no sense for a decentralized system. Its a contradiction in Steem's very purpose.
Uncapped influence based on how much you have staked leads to an all-or-nothing system. This is a problem because most people on social media sites are whimsical and that's just not likely to change. Where is Myspace? My point is that if a social media site demands large investment to get anything out of the deal that its a non-starter strategy.
Saying all that, allow me to make my key point for both the last comment and this one. I'm trying to explain that the market seems to be telling us that our rewarding system based on stake won't work, but that doesn't mean DPOS doesn't work. Resource credits are a brilliant idea and it makes perfect sense that SP stakers receive benefit through a delegation economy of RCs.
Perhaps the world will not accept the notion of whale/orca/minnow/plankton vote levels. We might need to make voting for the reward pool equal, however, the resource credit system can still compensate whales through a delegation market of RCs. The RC system is an excellent way to reward investors because they benefit from all the many communities that desire access to the Steem network.
People are claiming that SMTs will solve the disparity problem and downvoting harassment. I strongly disagree on both counts. The problem with SMTs is that they will almost always be practically worthless. STEEM/SBD will remain what people want because its a universal internet money, while most SMTs will be hardly better than wordpress token features that have been around for years. In order for a token to matter to anyone, it needs to either be useful in many places, or the one place that you can use it needs to be incredibly popular. And this is why the STEEM reward pool system needs to be palatable to more than just early investors like a common pump & dump project, but to billions of people.
