The tweet you see there is just as it is, they have already explained it all. Trumps comments are what's keeping the stock market stable, that's what they are saying. But I don't get what you mean by producing and selling your farm produce for a scam money?? What are exactly are you calling scam money?? Is it fiat?? Sorry but that shows you know nothing, because there is nothing as such. Even the cryptocurrency you're talking about that you think is best is very volatile. If you think the dollar you're using is a scam then why not switch to cryptocurrency and stop making use of fiat? I know you wouldn't, because you know that you can wake up the next day and all your money are gone.
Any person who wants to sell his produce in a global market today needs to accept fiat payments (unfortunately). You may be able to sell a few fruits here and there with crypto but at a larger scale it just doesn't work yet. I believe what he means with "scam money" is a centralized currency that you don't control, and that any day can be easily confiscated by the emitter (not the case with crypto).
