No disagreement really. I view it from my perspective as a hobbyist. I enjoy being in the shop working -- and I enjoy making stuff like my work bench, my saw tables and dust shields, my French cleat shelves, etc. I don't really expect to save money (if I do the numbers) so much as I expect to get more out of the process (skills, tools, etc.) than what I get buying something off the shelf. And yes - a professional most likely values their productive time over time spent making jigs, etc. so they will often allocate capital wisely to save time!
