No, please don't.
The issue is already overly dramatized.
It's not the nicest thing to say, but how I see it generally is if videogame is making you angry and disappointed, makes you cry and wreck your sanity and wrist too... it is time to take a break. Be it with crafting, raiding, shitposting in Limsa or pining for house.
It is not worth it.
Most important things in life are free.
Second most important cost pretty penny, be it real or videogame money. But second most important things are secondary. You see?
Locking people out of content because they weren't quick enough/ didn't abuse the system is wrong IMHO.
And I got a house and a mansion for my FC and I didn't abuse the system. I just got lucky.
And talking about quick: if I dodge an AoE in time, because I was quick enough, am I also abusing the system? Because that's what you're saying.
It's just a sad reality that there aren't enough houses. Someone will always be left out. But if I stop playing my plot will get demolished and then someone else can have it.
One thing I do find shitty however, is that you can own more than one plat becausecof account magics. That should totally be discouraged.
