You're 100% right. You don't get points for being able to shoot the ball into the stands from the free throw line in basketball, either.
Some irons are made with stronger lofts to offset lower COG and "springy" faces, but in general I think that stronger lofts mean you need more wedges, less long irons, and end up with 8 clubs that hit the 8 distances you need either way. If you are pumped that you can hit your 23deg 6i 210yds, but then you're going right to a 5w, more power to you bro.
Last I checked no one gives a f*** how far you hit your 7i whether you shot a 70 or a 117. Long and short are both misses.
