Correct. Arii's complaints about people promising to buy and then not is just the way it goes.
My wife and started and later closed a clothing brand and saw a lot of people who were "definitely" going o buy (my wife has a lot of followers on YouTube), but they didn't.
Our business failed for multiple reasons, but the biggest one was our productionn partner was (is) a criminal who stole our intellectual property, and by the time we caught on and thought about making a change the window of opportunity for a start-up like ours was pretty much closed (among other things). Enough whining!
Your point is spot on though. My wife was making videos at the time and the clothes she designed were outstanding. That is what brought the success - having a product that her followers wanted.
