Scripting doesn't really achieve very much, as I posted here enabling all the scripting operations only really allows more complex multi-signature transactions and proof of work in order to spend transactions.

There are a lot more uses than you've listed there. For example lottery transactions, and those puzzles you dismiss as "stupid" enable secure atomic cross chain trades, making payments that securely depend on an external zero knoweldge proof, and making highly private coin trades.

Yeah, I don't get why they permanently disabled multiplication. The explanation says it's because of possible bugs, but come on, it'd be pretty hard to fuck up a simple multiplication.

Because multiplication increases the size of the data. Load a 510 byte number, then keep DUPing and multiplying. Each operation doubles the storage, in relatively few operations all nodes are crashing because they've run out of memory. Your dismissive response shows an extreme carelessness which would virtually ensure the existence of vulnerabilities. Even the simplest operation is easy to make mistakes in. Fortunately the people working on the software are more considerate than that.

What's the point of having script

Because you can go and put new things to use without first requiring a risky network upgrade for everyone. Some of the non-standardness is also required to preserve forward compatibility so that new things can be safely and non-disruptively added in the future.
