The issue I take with your new scenario is that you're not the one swinging the club. You've been working on your stance, grip, and follow-through, but none of that is relevant because the clubs Tiger uses are 400 feet long and in space.
Again, your premise is just strange. If you are using an auto-guide setup tracking on its own, then you're really not working the hobby as if you had your eyeball on the eyepiece manually tracking a guide star on an alt/az mount instead of equatorial mount. At this point "hobby" is really undefined in context, so saying that someone with more expensive toys is any less of a hobby than someone with less expensive gear is just moving the hole while someone is on the tee box to continue with this wild comparison
If you do grind your own mirrors, more power to you, I've thought of taking up the hobby myself.
Also I do happen to know at least one guy who grinds his own stuff. Legend.
