You're not talking about making him a judge, you're talking about nominating him to be a judge on one of the top courts in the country -- without him ever having done the job at any level. It's very much comparable to the surgeon with no hands-on experience.
No, it's really not comparable. A judge can take plenty of time to make a decision, read up on whatever s/he wishes to for their decision, et cetera. A surgeon has seconds, or at most minutes, to make a decision under pressure, with at most time to ask another surgeon for a quick consultation.
