You have to get bookkeeping exactly right.

You have to get crypto exactly right.

Bitcoin sits on top of both of those sharp pyramids.

Yesterday someone on HackerNews compared a Bitcoin account to a pressurized system where the slightest failure means you lose everything irretrievably and instantly which is a great analogy.

You don't need Good Enough for this. You need Perfect for this.

No you don't need perfection to add some basic controls that would have prevented most of the damage here.
