As it stands, I'm likely going to be buying Ikea-produced furniture next year because I need to furnish an apartment cheaply, and I will only be keeping it for a couple years. I don't have the money or the means to buy furniture that will last me a long time at this point...but that doesn't mean I'm not thinking about what I am doing. I still am aiming to buy as little furniture as is necessary, and avoiding anything I can do without or simply don't need.
Yes, the idea is simplistic, but that is the point: if you can reduce and purchase quality then you should, and if you can't, at least have an awareness (and perhaps simplify another aspect of your life). I'm at a point where I can do both, but understandably, not everyone can do that.
It's all about reducing as much as you can, within your current circumstances. I'm not trying to say that you need to buy that $100 knife now, but in that case, perhaps you could do with one or two less forks (this isn't a literal example, mind you). Less waste and less worry, without entirely sacrificing comfort.
