DPS display could easily be solved with a system already in game.

Irrelevant stuff

Where are the consequences currently and why aren't they affecting you and other people en mass?

Their concerns, in most cases, have nothing to do with the fact that harassment is still against ToS. It's the frequency and the eventual look to have another tool to separate content, in this case, a wall set up by players to do even content like EX fights by having unrealistic expectations (i.e. requiring FCoB gear numbers to do LEX). By frequency, I mean the increased occurrence of douchebags being douchebags.

Just because something is against ToS doesn't mean they won't do it. Case in point: parsers (due to requiring a 3rd party program)... bots, hacks, buying gil, current harassment or violations of safety and privacy, etc. Their side isn't saying that it won't happen anyway, but they're arguing that the frequency is minimal at most right now, and they (along with the devs) like it that way. Speaking from experience that's why, it will happen far more often. Just as you use someones raid progress in this game against them, so too will someone use their actual numbers against them (irrelevant of their potential because of circumstance like gear differences). It's just one more thing to make people hate the game and the community that exists within it. If the devs see fit to ever make it official, then so be it. The side that doesn't like it will have to deal or leave. It's as simple as that. It doesn't change the fact that the devs, as far as we know, still don't want it to be an official thing for similar reasons that the players here are expressing. It also doesn't change the fact that a simple workaround, like the one I suggested, exists and the devs are A-OK with it for the most part.

A wall only exists when there is a DPS check hence the reason people primarily in the parser camp that do use parsers typically participate in endgame where there are a # of DPS checks. The reason you won't see extremes such as the LEX example you provided is because when content is nerfed and when player(s) are overgeared for content, DPS optimization is not a requirement. We can speculate all day about how the community will handle parser's but as you can already tell by the masses that use them, people rarely abuse them in outdated content. And it has nothing to do with the fact that they are outlawed by the ToS which is my point.
