I don't think anyone was saying it's a bad idea...I think, speaking for myself at least, that many of us who have been down that road have realized it's a whole lot more work than we expected, it's filled with frustration and sweat and sore arms...and turns out it's not quite as glorious and satisfying as we thought it would be because ultimately we just did something the hardest way possible.
I say it's important to learn all of these hand tool techniques, practice them some, maybe build a piece or two from start to finish that way...then buy a few machines. Because - again, speaking for myself - I find labor in the workshop to be a monumental waste of time. I have so little of it already I'm not gonna squander any of it on apprentice work. It just defies common sense to do so.
Maybe if I was a retired old man who needed exercise or something it might be worth the effort. But I think my desire to build as many projects as I can before I die would still trump it.
