What you say is obviously true, but there must be some curve between the effort needed to make it useful and the utility derived from it, based on which some people can rationally decide that it is not worth it for them, while others can decide the opposite. That doesn't make one of them lazy and the other one stupid (although some people might be better or worse in estimating the effort or the utility of the process) - notice that otherwise the same generic argument could be made for anything: "X is what you make of it ... walking away from it is a lazy solution." where X could be nuclear weapons, hard drugs, etc. etc.
