&gt; The Catholic Church can&#x27;t even reliably enforce chastity among its professional clergy<p>Many of the Catholic Church&#x27;s problems stem from the fact that members of the clergy are in positions of authority and trust which can be abused to gain access to small children, one key reason that these positions were abused in a way that would never happen to, say, a company full of <i>actuaries</i>. A Mars mission wouldn&#x27;t have this problem. It also has much smaller staffing needs, at least for the time being.
