Something has to dry out to guarantee the PCB is broken within twenty years
to provide assurance that new hardware is always marketable.

Electrolytics provide functionality of spontaneously blowing up every once in a while.
They also don't mind slowly leaking, causing corrosion of other components (Kamikaze style A).
They are also masters of manipulation, and might choose to maintain composure while
malfunctioning, causing the customer to discard an entire PCB (Kamikaze style B).

Incidentally, they store electrical charge or something.

How much of this is necessary? Rather, how often do hackaday people get down to alterations on individual capacitors and resistors and what not like that?

Can't a lot be accomplished at the component level? Where do "you people" [ ;) ] find it useful to go down into the little nitty-gritty parts?

Capacitors tackle dc voltage. This is really necessary for a pack of circumstances. You'll use a pack of small power capacitors crossed logic ICs to "de-couple".

Capacitors also "smooth" out waves in charges, that's why a largish capacitor is used in energy supplies - to overcome the "ripple voltage" whatever happens from rectification (using diodes to convert AC to DC.)
