You can even beat the last level in the game with just a single grabber if you want. It's just a lot more tedious and annoying than using multiple grabbers.
The beauty of the game is that you can choose what you optimise for. You can try to make it as small as possible, or as cheap as possible, or as fast as possible. Or you can ignore all that and just try to jury-rig a solution as fast as possible.

>None of this is explained well IMO.
What is, the fact that you might need to use multiple grabbers? I found it quite obvious that you can drag out multiple of any given element, given that there's no indication of any sort of getting "disabled" or "unavailable" after you drag the first one out, so there's no reason a second one wouldn't be usable.
