1. The tiny little baby foreskin requires much less cutting than the huge developed 16 year old's foreskin. Hence less pain is a real possibility.
2. The psychological pain at 16 results from, for just one example among various possibilities, being aware of what is about to happen, possibly days or weeks in advance, & the associated anxiety about the pain involved. That's quite common with surgeries on adults.
3. Irrelevant to the topic which concerns the best time to circumcise if one is absolutely going to circumcise & the only issue is when or why not at 16 rather than as a baby or another time. Scientific evidence has found that at 8 days is ideal.
4. At 16 the minor can offer resistance & make a foolish decision. It's better that parents choose for the baby. Otherwise their child will miss the only opportunity to have it done at the best time for their child.
5. Irrelevant. Does not address the point made.
Circumcision prevents STIs & other problems & saves millions of lives from HIV, cancer, etc.
"... the argument of “informed consent” is easily demolished by the fact that we routinely vaccinate our children against disease without their consent for their own good."
