This is all valid and a good point. An interesting observation to make is that all of these time-savers relate to paying someone else to maintain a possession of yours (house, car, lawn). In this sense, minimalism saves time too (no possessions = no time spent maintaining them). It also saves money (from buying the possessions in the first place and paying for their maintenance thereafter). So then the question is are there other ways you can use money to get more time? Good argument for better healthcare all else equal, but yes, the larger point still stands.
