I'm pretty new to the cryptoverse, so my understanding of it is necessarily limited, but its in the nature of certain things that they are more of a concept or ideal than something that can be attained. Infinity is an example. You can never reach infinity. Perhaps decentralization is another. And while a degree of control is possible, as in your example about Twitter accounts, in practice it would be difficult to achieve without a lot of effort--bearing in mind the law of diminishing returns.
