I buy AppleCare and leave the screwdrivers to the Genius Bar. They have copies of them on all of the continents I travel between; I frequently do not.
Furthermore, who wants to be in the laptop repair business? I push bits. For a few hundred bucks they'll fix anything that breaks and I can stop being the Maytag Man and get on with life.
I take it you do not visit Poland or Trinidad and Tobago often. Fair enough, to each for their own needs! But keep in mind the grandparent is not necessarily a high-flying high-paid bit-pusher like you, so your dismissal is still a little self-centered.
(Should I mention that it took two standard-size Phillips heads to replace my screen, the kind of sizes frequently found in a basic swappable-head screwdriver?)
