The problem with this philosophy is that at some point you are simply playing God with your own opinions.

For the readers, it might be interesting to know that smooth is a member in the core team + also has a large stake in MEW hinting that he is one of the most involved people in Monero. If they make bad decisions in the core team, his personal investment also suffers.
The beauty of MEW is that everyone may voice their own opinion and vote for it, and the majority wins. Even then, the core team may totally independently decide whether to act according to the guidance or not.
Mostly, the matters that MEW is interested in do not even require the core team to implement. In these cases it is very easy - the burden of implementation rests totally on the ones who voted in favor.
MEW is not trying to force the majority opinion on anyone. The rationale for voting is to measure the support on initiatives. For me personally, it would be a great tragedy if I spent my time doing something that most would not even want to use. Submitting my ideas to economic vote before implementation, saves me from many griefs.
