"scarcity creates value" is true in general but don't take it too literally. It depends how you define the perimeter, hence it doesn't work here. I already have friends I've introduced to Steemit and after 2 articles they tooke their business to trybe.one 

There's scarcity for RC in steemit but there's no need for anyone to socialize on steemit as more or less the same thing can be done on many other platforms (weku and trybe are two of them)
