It may sound a little offensive to some, but if someone hasn't been able to understand what Bitcoin is in 15 years, will they ever be able to understand it? Somehow I don't believe that people in general are that unintelligent, but rather that most are heavily influenced by what politicians and media say, which tend to glorify centralist beliefs.
this is a big problem for bitcoin. even though it's a logical system, even though it aims to liberate people, even though it provides decentralization and true ownership, it means nothing if the people in question find it complicated, if they don't buy into it.
the power of bitcoin and people's use of it are mutually reinforcing. but if people like their labor being wasted, if people like making the rich richer and richer, that's their choice. it's not an all or nothing situation, but it's very important that people prefer it. otherwise, if i own all 21 million bitcoins, it's useless.
