There were teenage lieutenants and commanders (of ships) in their 20’s in the Royal Navy in the 18th and 19th centuries. Even a sixth rate ship had well over 100 men on board and smaller, unrated ships could have a complement of about 100. I do think there are lots of advantages from experience, both on the technical side and with organising teams but I don’t think it’s totally crazy for young people to sometimes be very useful and productive. Plenty of the companies YC funds are founded/run by people in their (often early) 20’s and some end up being managed well and others poorly. If it were the case that young people so obviously weren’t able to do it, I would expect YC would have changed their behaviour by now.
