Relevant xkcd: Average familiarity
You severly overestimate the average persons tech literacy even when you try to correct for it. Booting from USB is already a really advanced topic.
Though creating a lemmy account is not that complex. Typically all you have to do is fill out a form on the websiten instructions included. The problem there is not the tech literacyn but the willingness of the people to even interact with systems they don’t know, like finding a home instance or understanding the concept of the fediverse. Most people could create a lemmy account, though also most people wouldn’t.
Maybe someone has more history knowledge than Wikipedia in this case: Were the Young Pioneers inspired by the Scouts movement, which was startet 1908 by Baden Powell? Or more by nationalist youth groups that followed them (like the Hitler Youth in germany took the traditions of scouts and the wandervogel groups and contorted them into violent nationalism)? Is there any connection?
