You know people will sell anything to get more gill , even titan HM which is an old content I see some groups sell it in pf .
Crafters and gathers can make more gil by gather/craft , so what experience players do ? They sell runs , not saying all but most who have 7 good players to get the job done .
You think everyone will keep buying coil every week to get his/her loots ? So what if this person gona waste all his gil on that ! Then be it , I think whoever will buy it will be one time like t5 these days .
Most of us cant play with their friends cuz of coil so they forced to leave fc , servers to find a static or a good pug parties and thats sad whwn its seem the game is all about coil .
Why not try it and see , I think SE can make it work .
