Dear Avira,
The list is not at all exhaustive. The point is that these are all serious endeavors in the modern day. Whereas, our ancestors barely thought of these things.
One Senior Talmid Chacaham that I’m close with had to attend one of two fundraisers. It didn’t work out for him to go on the three day cruise, so he was at the pidyon peter chamor instead. He remarked that on the cruise he would have been involved in Torah non-stop. Whereas he ended up just watching someone else do a mitzvah.
The point is that the yeshiveliet today are much more involved in these things even if, or maybe especially if they know less than the learned of previous generations.
