In the below transaction I know why the scripts are needed. The question I have is why can't you just do something like:

input_txid + output_txid + HASH160(pubkey) + amount + fee + signature(input_txid + output_txid + HASH160(pubkey) + amount + fee)

Hoping for some input, good or bad.

Code:

Scripts allow you to do other things since they specify how you that output can be spent. Those allow special nonstandard transactions for both experimenting and creating more features.
