The reality is - a small percentage of treasuries are owned by individuals (including - and mostly - 401ks) - I linked to the data above.
Anecdotal evidence that you helped some people buy treasuries does not dispute that.
Something like ~5% of treasuries are not owned by The Fed, Foreign Governments, Pensions, 401ks, and Banks.
The vast majority of that is owned by bond traders. You're talking about maybe $600B owned by a group of people that has >$30T in wealth. That is basically nothing.
