Well Said.
There are many things that can kill your PC just as dead as a
lightning strike, and not all power surges are caused by lightning.
Don't fixate on one threat. Full offsite backups are the only real
protection against lightning, or anything else.
A small UPS addresses so many potential risks properly that even if it
isn't the unachievable, theoretical perfect lightning protection you are
much better off for having one.
full house protection was mentioned in this thread (by me). I think
it's a good thing but it does not eliminate the need for a small UPS
on an important PC.
If your house takes a direct hit there _will_ be damage, even with the
ideal grounding system.
