I don't know why people complain that "filthy non-crafters" are getting knots/sealants and selling them. You know these aren't the easiest thing in the world if you don't even have one high level craft, right? Most of them are easy, but if you have to forfeit one for the day because of something like High Wind in Ishgard because it takes you an hour to make one HQ of the three needed (because you have no useful crossclasses), that cuts into your daily knots.

Furthermore, the time investment. I'm bringing up alts that happen to have 50 CUL already and it's still going to take a week before I have increased sealant production rate. Judge the market in a month when insane no-lifers have it on farm with multiple characters. Price will drop, supply will go up.
