I believe we can read further into that, if one reads AMs writing more fully; that making it fun is not necessarily making it easy.
I think that confronted with the need to alter a course, AM encountered many committeemen that began the process from the wrong perspective to begin with. He was probably frustrated that a bunch of stoggy old men rose to committee status at their club who were calvinistic and stern and as technology and such may have suggested lengthening and resetting hazards, that they began with the notion that it must also be altered to play stern and unforgiving, with little option but to play one way precisely. I think AM was trying to tell them that the stern one way - the hard way was a boor, and that one can make it fun through diversity of design options and creativity.
Quirky and unfair holes, or too short and booring ones need alterations. AM just was telling them to not go for the narrow stern test, but include pleasure that comes from challenge with creativity as well as pleasing compostition of design. More people can appreciate that. It isn't that they must all have an easy par or bogey. It is that they should feel enthusiastic to play with interest and creativity, not fear that one misstep is a disaster and only the best can ever matchup with the design of the hole.
