The burden of proof is on the side of those who are asking/demanding for such a system. We have provided more than enough proof to our side in terms of SE's stance on P2W services like one suggested here which converts real life money for in game gil at which point can be then used to gain a vast array of in game advantages like buying runs/loot, housing, gear, materials and more. We have also provided evidence that the occasion like with ring/bracelets, SE stance was they are against anyone misusing it to gain in game financial advantages and that if people keep doing it they will be forced to change it because it is not being used as intended. We know for a fact the cash shop was designed and being used in a way to keep such P2W advantages out of it.
So we do not need Yoshi to come in here and tell us what we already know which is they have no plans to implement such P2W systems and that their stance is against such systems. You are also not neutral, you have taken a stance on the issue and as such cannot be considered neutral anymore, your stance being you want it and are arguing for it. It is that side of which you stand on the other hand that has kept trying to claim SE is going to do it despite evidence to the contrary. We know for a fact Yoshi is happy with the current system as shown in the interview Tiggy linked too which also showed they have done the research and over 80% of people are happy with the current system. The rest I assume can't be that unhappy about it or they wouldn't be here still.
I know for a fact they will lose customers if they abandon their stance on this issue and allow such P2W systems like one mentioned here, I am one of them they would lose among many others who have in the past said such on here but they will not lose you as you already said your content here with the current system and they would probably not lose anyone else if they do not change their stance so the burden of proof is again on you to prove that the new customers they might or might not gain would make up for all of us they would lose. Also as Yoshi said himself "...just because ESO moved into a free-to-play subscription model, it doesn’t necessarily mean for us to move into that direction as well." "...we don’t believe that FFXIV needs to shift in that direction and not everything that other competitors or titles do will necessarily apply to our title."
