but aren't these explanations leaving out the fact that the market has to buy long-term US debt at an interest rate they find "acceptable" not buy some Central planner? In other words if the market doesn't want the bonds, then the issuer (US gov) forced to increase the rate to get people to buy them. Then the bond market will reprice older bonds (less attractive rates) at lower prices?
The US gov can and does of course "force" sovereign entities to buy the bonds at whatever rate they set, if they don't, the US threatens them with sanctions or nukes.
