The laziness is with the quick-buck investor parasites ruining every other hobby and those people are much more likely to be older in order to have the money and boredom to commit to speculative, glorified hoarding. I do think laziness partly factors in to the reason bikes aren't so mainstream, though. Baseball cards and such are just a matter of locating and paying—not much to restore, there—and storage is much easier. Cars are the closest analog to bicycles, I think, and the parasites can consult investment experts or websites to see what models/years/trims/bodies are most valuable within their price range or are considered to be undervalued, have a car inspected, bought, and sent off to a restorer to be picked up a few years later all remotely and the rising values of them as more and more parasites flood the bubble market hoping to cash in at the lower end before it pops makes ever less impressive and more common older cars more cost effective to restore (I used to see all manner of interesting old cars on nice days, but now it's fairly rare to even see a TR6, though lame new lower-end exotics aren't hard to find). At the very top of the market, the 7-8 figure concours cars get international coverage even in non-industry specialized magazines that reach a very wide range of people, which bikes don't get. One of the most disappointing things I ever attended was the Pebble Beach Concours (the other was KMFDM, who just phoned it in that night, dammit). It seemed the majority of owners were just barely interested, un-knowledgable check-cutters merely there to wallet dick swing and hoping to get an award to increase the value of their investment and a lot of the crowd was infested with D-list celebrities trying to get noticed by C-listers. I think half of the people there were in a single episode of Law and Order. Even the highest end bicycles don't leave much room for profit if someone is paying locators and restorers to do everything for them. Which I would like to add that the bike collector obsession with original parts and paint even when they're completely unusable and 99% rust and disdain for even good repros keeps them less accessible. Sure, originality is valued in automobiles, but plenty of valuable concours cars are built off little more than a VIN plate and a scrap of metal (I remember reading about a dispute over 2 Jaguar D-Types that shared a VIN—one had been built off a found engine and some other parts and the other had been built from a wrecked chassis or something along those lines). Bikes require the careful restoration and locating of parts like cars, ever more expensive chrome in some cases, and are ultimately seen largely as being for children or spandex dorks. They don't have the same cultural significance or embody the nostalgic vision of an era in the way cars do and aren't as often wrapped around the kind of memories one tends to have when coming of age with a license—almost nobody has memories of picking up a date and feeling them up for the first time on their Schwinn, but a lot could be done in a $500 Subaru wagon. I can see a Duesenberg and day dream about offering my hand to Hedy Lamarr as she steps off the running board in front of some fancy restaurant filled with gangsters and classic film stars or making out with Yvonne DeCarlo in a Facel Vega, but even Pee Wee Herman would have trouble shoehorning a bicycle into fantasies like that. Bikes are also largely a solo experience as, even riding with a group, you're still separated. Even with tandems, you're sitting in line, not beside. Bikes are just kind of stuck where they are in a realm of more limited appeal, but I don't think it should be anything to lament. Do we really want parasite investors infesting this hobby, too? Sure, the value of what you already hold would go up, but you're closing the door to new people getting into the hobby because they really like old bikes and, when that happens and who's left to sell your beloved bike to?—parasites who park it in a storage facility with a bunch of others like the warehouse and Raiders of the Lost Ark? I certainly wouldn't pass up a massive check for something I bought for a lot less (like the Alfa Romeo Montreal I almost bought for $25k just before they bounced to around 6-figures), but you might want to ask what you're in it for. Me, I'm not a collector—I only have the one Iver Johnson I bought because I like the style, old-school quality, local history, and idea of riding something so old while the rest of my bikes are low-value customs—so that's my kind of outsider perspective on it.
