Ah, there it is. The final argument to end all arguments. How a house owner earned every single plot in his or her collection. With how plots distribution works under the current housing system you've won a lotter (especially if it's a Shirogane house). You may employ all the mental gymnastics you want, but winning a lottery isn't earning things. Just because you and that Random Internet Person did exactly the same things and followed exactly the same steps. You have your house, that Random Interned Person doesn't. Does it mean he didn't earn it and you did? Nope, it just means he wasn't lucky enough. At this point I'm beginning to hope SE can be convinced to go through with this proposed change simply because arguments employed by multiple plots owners are getting worse by the day.
You haven't said anything about a weekly income, but you're getting upset over the fact that people may not have the money to spend on house decorations 2 weeks after obtaining their plots. How dare they not have enough money yet. How dare they not be willing to spend money on cheap items they don't want to satisfy your aesthetic needs regarding plots that aren't yours. Outrageous.
You haven't been given any reasons why you'd want to relinquish your additional plots because just as you don't care about players that couldn't get theirs none of the players involved in this discussion care about you or what you want. No one is trying to convince you because: a) that would be a futile attempt anyway; b) you're not the one that needs to be convinced, devs are. That's how feedback works.
Assuming that people loosing plots would be upset about the whole deal one way or another taking 2 plots away from 1 player is always going to be better option than taking 2 plots from 2 different players from the point of view SE have. Again, needs of many vs needs of the few.
That those 2 players don't deserve their plots? They've won them in the great lottery of post-maintenance rush therefore they've earned them. And here I thought you aren't more deserving than other house owners.
