i am reading stuff, like HN, and a topic comes along that is considered controversial where i live. i do not want it to show up in my browser history.

so i right-click, open link in private mode, or in a tabgroup.

i am done reading, i close the private window or wipe the group.

with your method i'd have to first start a new browser with that second profile, then copy the link to the new browser to read. that's a lot more work than just selecting an entry from the right-click menu.
