There's a certain level of minimalism though that actually increases spending. For example, not keeping a toolbox around the house means having to call someone for even the smallest maintenance work you might need.
You seem to be deliberately missing the point, if you need tools then keep them, the point is to own what's necessary rather than what society and marketers think you should.
Not keeping a tool box around the house very rarely means not having access to tools. Tools are commonly borrowed/shared amongst friends, family, neighbors, co-workers, borrowed from work, co-ops[1], makerspaces, or rented[2].
