This is Trump we are talking about and he would say anything to that would "make america great again" somehow yet he doesn't know how hard it is to go back to gold standard nowadays, it is way too over leveraged to go back to that now and we are talking about not even close numbers so in reality he talks the talk but he won't be able to walk the walk as he has done it a lot of times.
When April 2022 comes and he does nothing about it, dude will literally just say "I never said it" and with even proof with the video dude will be loved by many republicans just because they love an idiot like themselves and will be supported by many republicans who may not like him but prefer him over the "demlib" for some reason, even if it means country going worse, they rather go worse with a republican than get better with a democrat.
