I actually really like this analogy - you can get away with using a handful of tools (an Allen Key, maybe a screwdriver and a hammer) and get a table.
Or you can use all of the tools (planes, saws, maybe a lathe) and get a more robust table, that is more stable on an uneven floor, and is the perfect fit for the alcove you want to put it in.
Either way, you still have a table.
