Or more. After clearing out more space in your home, and thinking "mindfully" about what you like and don't like, you could just as easily become more interested in acquiring new things than if your home were already "full" and you weren't thinking about things. You could be right, and I'm somewhat curious to know, but I'm not aware of any evidence either way, and I'm skeptical that such certain claims may be based more on a fashionable type of utopian theory than on real-world evidence.
