The problem is it might cost 5$ to buy, but buying it also takes effort. IMO, the way around this is to keep a good multi tool which is a so so version of a lot of things and then only the real tool if you are going to do a real project.

Cellphone camera good enough? Ditch your actual camera.

Your cell phone camera can act as a camera but not as well. A multi-tool usually has one Phillips and on slotted screwdriver. Of course those are never the sizes you need.

There's a point where it becomes very hard to reduce item count without greatly increasing the frequency that the task at hand can't be performed with the existing set of items.

A Philips screwdriver may or may not be used for a year, a multi bit screwdriver has much better odds. But the trade off is all about frequency. If you need to swap license plates not having the correct tool is not a major time sink. Rebuilding an engine and you need the right tools.
