A full grown adult standing with their full weight on their Aeropress can achieve about 4 bar of pressure; standing at the counter, pressing with one arm as hard as I can, I'm unlikely to achieve more than 1 bar. For context, an espresso traditionally requires 9 bar to properly extract. It's doubtful that that even 1 bar of pressure makes any difference to extraction at all.

But assuming that it does, and you think that pressure is a good thing - why on Earth would you instruct people to press "gently"? Now you're looking at more like 0.1 bar of pressure. That's definitely negligible, certainly not "high pressure" or even "relatively high".
