You make some good observations and I have to admit that I'm just as reluctant to have someone else depend on MY skill and judgment as I am to rely on theirs. I am totally willing to face the consequences of my own actions--however dire the outcome--but would not subject someone else to same level of risk. An agreed level of risk is essential to a 'team', IMHO. If one finds a person or persons with like risk thresholds and similar judgments about the risk, teamwork is possible and desirable.
