You're green ink has gone off colour, are you feeling OK ? Maybe time to see a doctor.
Anyway, to your post. Your original objection was to being dictated what shot or length of shot to hit which I answered (successfully). You then came up with a number of objections that in essence are the reasons why a par 3 course isn't a practice range. All fair points if you want a practice range to start with but I don't think that was the point of the question.

Do you think that par 3 courses would be used more if a) they were kept in the same condition as the main course, and b) they consisted of proper golf holes with some design input rather than random areas of mown turf ? I've seen quite a few par 3 courses that have had minimal upkeep and are absolutely featureless, and have never felt the need or want to play any of them. The only one I have played was the par 3 course at Valderamma which was a proper golf course, in good condition and was a blast to play.
Also tend to think that par 3 courses would appeal more to visitors as a bit of an add on to their golf "experience".
