Yeah that totally contradicts where I said he could keep it safe, oh wait.

The text is outright telling you, eventually Sauron would get it. Not by “steamrolling” anything. Tortuously, through the use of all his power, with several hint-hint comparisons to the world itself having no strong opinion. Not because Tom Bombadil is any less capable than some half-pint farmers and a few aristocrats. He’s filled to his feather-topped brim with bullshit magic. But the power to defy the enemy is not within him. Frodo shows him the ring and he barely gives a shit.

You’re arguing like I think he’s the bestest OC ever, donut steel. Nah. He’s Roger Rabbit. Eddie gets handcuffed to Roger, they barely survive some shenanigans, and when he finally gets a hacksaw to separate them Roger slides his hand out so he can lean in and watch. Eddie understandably throttles him, demanding - “You mean you could’ve done that, at any time?!” Roger tells him: “No! Only when it was funny.”
