Dont need to build a match....there is more then one way to skin a cat.
You can use flint and steel to start a fire
A bow and string
Black powder
Even just rubbing sticks together it is possible.
So what the big deal? Just because the match is gone doesn't mean human ingenuity wont persevere....Or we lost all intelligence when the factory burnt up.
You still lost matches.
The point is that technology can and often is lost, and replacements are not necessarily equivalencies. Loopala's right: I can drive a car, and even do most repairs - up to and including swapping an engine. I can't, however, fabricate a replacement driveshaft from raw metal.
I could probably build a really clunky zippo lighter, though. My zippo certainly wouldn't be as good as the professionally manufactured one, but it'd light a fire.
Do you think I'd win a fire-lighting competition against a guy with a professionally-made zippo, though?
THat's kind of the point - fabrication is different than installation or repair. The human race HAS lost knowledge, and while things can be reinvented, the more complex the system, the more time and resources are required to recreate it.
If I hand you a pile of sand and a broken telescope, could you fabricate the lenses - right now? You don't get tools - you'll have to make those, so, you'll have to build something to melt the sand, something to purify the resulting glass, some way to cast the lenses - without bubbles or imperfections, some way to mirror them, some way to align them...
An invention - even a match - isn't just a thing in itself. It's a combination of lesser advances all built together to build something larger - everything from the wrenches to work on the machine to the steel in those wrenches to the machine itself.
Ever change a fan clutch on a 90's ford? They make a special wrench to assist you in removing the fan clutch, as standard wrenches don't really fit on the clutch itself. Without that wrench, it's nearly impossible to get the clutch off. Could you fabricate a new wrench? How many people can? IF you did, do you think you'd put it into mass production, or would you toss it into a toolbox when you're done - and would someone else junk their car instead?
(Edit)
I work in tech - here's a good one going on right now. When's the last time you've seen a Jazz Disk? Howabout a working Jazz Drive?
A buddy's company has an old archive, taken on Jazz disks, that includes a unique algorithm for a targetting system no longer in production. The system is obsolete, but the algorithm cut the resolution time of the targetting array by about 40%.
Unfortunately, the notes and design of the algorithm only now exists on these Jazz disks. If they can't find a way to read 'em, the algorithm will be permanently lost - and it was the product of inspiration of a programmer that is unlikely to be replicated.
That's /now/. Right now. In the age of the internet.
