Its not controversial and i also do that after hanging out with friends but it matters how u say it.
Anon would probably go “thanks for hanging out with me” which would sound kinda depressing but i guess the people in this hypothetical scenario were aware that he was a loner so it wouldnt be an issue actually.
WTF? Why?
Me and my friends always thank each other after spending fun time together, how is it even controversial?

This is a (micro-)cultural thing. Common for some groups of people, really uncommon for others.
