Minimalization. A very poor argument.
The pens cost $15 each. Not $15,000. Trump loses more presidential golf balls in a day than the cost of a pen.
Actually, I played quite a bit of golf when younger.

I golf too. Overwhelmingly, balls are lost on the tee shot or when hitting over water hazards. 18 holes and 30 pens means losing 1 2/3 per hole, every hole - 5 balls every three holes. Trump isn't anywhere close to that bad of a golfer. Hell, even I'm nowhere near that bad, and I play a lot less
If you're trying to tie the cost to only one pen, I'm seeing a three pack of DJT presidential seal golf balls at $12.95. I don't know if he uses them or just gives them out as souvenirs, but he probably doesn't pay retail. But even at retail, he would have to lose (as opposed to giving away) more than three balls per round. Unlikely
