Reducing a methodology to a single phrase is bound to be... reductive. But if memory serves there was an example her book where at one point she did, in fact, get rid of her hammer and either used another object or borrowed one when needed.
Speaking for myself: I have more objects that have utility than I have space to put things away, so there's got to be more to it than that if I want to avoid clutter.
She did, but later bought another hammer (I think it was a screwdriver actually) because she realised that it did in fact spark joy by virtue of being useful.
