Not sure I agree with most of that, and for the first bits, actually I believe all that actually is pro-digital argument, not pro-film. Assuming you store your digital pictures intelligently, your digital photos will never deteriorate. You get the same quality 5000 years down the road you get today, ceteris paribus. No matter how kid gloves you treat your film, it's going to break down over time and with exposure to the elements. Yes you don't have to keep worrying about storage standards, but at the same time, I consider this an over-exaggerated threat. Conversely, unlike with film, you don't have to worry about constantly buying a bigger house and a warehouse of storage products like dehumidifiers to contain your ever expanding collection of negs and trannies.
As to slides having better highlight detail, you really should give negs a go. That will blow your mind (yes, that was tongue in cheek). Seriously though, that slides have better highlight detail than a digital camera is a very debatable topic.
As, for that matter, is getting a better digital image scanning a slide than shooting with a DSLR.
As for the rest, it's all a matter of opinion and you're perfectly entitled to yours. Long may it last.
