I miss the cover design of 1Q84 and also keep some cookbooks around. The benefit was the same benefit as minimalism: less to move, less to dust and make dust, less to search for, less to put away, more space. You live in Europe so it's hard to convey how overflowing with goods the average American house is. My choices are a reaction to this and I still feel we own double what we should, but my spouse and kids feel differently influenced by the society they know (I am the only one raised abroad).

I own a Pi 3 and used to run a NAS, home assistant, and ad blocker but found Google Home and a Synology NAS to be easier. I also have privacy concerns, but balance it with time commitments.

One of those is commitments is cookiing Saturday mornings to save time during the week while maximizing health. Other than making a batch of whole wheat pasta, I don't cook during the week. Many of our calories come from nuts, dried and fresh fruit, and soy milk which we keep in ample supply. Is meal prep an answer to your convenience conundrum?
