The issue isn't just that some smart contracts are buggy. After all, all software should be expected to have bugs at some point. The bigger issues are that a)the source code can be very visible, making it easier to figure out how to exploit than traditional code running in an isolated server, and b)recovering from an attack can be incredibly difficult (such as needing to create a fork of the blockchain pre-attack).
