Quill stems and 175 crank arms are what I stash. And with two DA7800 machines, I try to keep an extra Shimano DA7800 chain in the bin. IME, nothing else shifts the terrific 7800 group like a 7800 chain.

what we really need is ability to archive a digital version of the parts, 'cause one day someone will be able to 3d print you one in the material of your choice.

This is so true! And these digital designs should be made public, not kept secret as intellectual property. Honestly, who's going to make much more than pocket money on reproduction antique bike parts?
Even now, there are a lot of stamped and folded sheet metal things (Nivex derailleur for example) which should be digitized so anybody can get them waterjet- or laser-cut from their material of choice, and make their own. With CNC machining, the possibilities are already near endless. Often the hard part is finding a proper CAD drawing to start with. Getting someone to draw up the part properly can be a huge challenge!

Well for a couple hunnit you can get your very own laser 3d scanner and you can scan and reproduce pretty much whatever bike component you want.

Sturmey Archer stuff pertaining to the British-made four and five speed hubs are getting very rare. The longer 6 1/4” axles and their specific indicators have become as rare as Hen’s teeth. The shifters too, are disappearing. These parts are not interchangeable between even similar models. The Sprinter Five speed control has a different amount of cable pull from the modern five speed shifters, even though they are both single cable actuated hubs. Of course, anyone looking for Stronglight 122mm BCD chain rings (or heaven forbid, Nervar 128 mm BCD chain rings) knows that future proofing these remains a challenge. John Vara’s Red Clover Components does make triplizers and a facsimile of the semi legendary 39 tooth 122 mm BCD chain ring for Stronglight 93 or 105, but the other offerings are dissimilar in profile and in limited supply.

That's long enough that I'm in more danger of changing a part to something else before I actually wear it out.

I'm guessing it's far too late to stockpile one inch pitch chains, sprockets and chainrings.

I think it's critical to acquire skills and tools. They can't take those away from you! I learned to braze, weld, and machine things just about as the SAAB parts and lab stuff really got scarce, so I was able to somewhat seamlessly switch over to making it myself. This is probably what I'll do with bike stuff as well. I've already made a couple quill stems and a front derailleur, along with a smattering of cables and other odds and ends for antique tandems. My dream is to get a shop with all the necessary equipment (CNC mill, lathe, TIG) so I don't need to rely on my workplace for it. I also want space to setup some baths for chroming and anodization. What's next? A foundry, I guess! It would be cool to cast things, at least small stuff in aluminum or bronze.
I figure I should be able to stave off most planned obsolescence this way. As long as bearings remain available, I should be good to go. Making bearings is hard.

Bike parts enough to last "my" lifetime.

Wonder if better quality rims with caliper braking surfaces will become endangered species with the proliferation of disc brakes.

I'm mostly worried about wear parts and non-serviceable items. Since my older fleet is MTBs I'm looking for 9 speed XT shifters and cassettes. I also want a SRAM Rival 10 speed group for my wife's road bike because she likes those levers better than 105. I suspect that 10 speed road stuff is getting thinner on the ground.

Wow, I didn't figure Shimano would make such a bold move. I wonder what percentage of sales of Ultegra are for Di2 vs mechanical shifting.

6600/6700 chains should suit just as well, and are significantly less spendy. As might the HG-95 in a pinch.
7901 chains are the business for any DA 10-spd setup imho, but they'll run you $60 - $100. More if you're in a hurry.
