High bandwidth protects you against basic DoS attacks that just fill up the pipe with garbage traffic.
The other problem is that bandwidth is usually harder to scale than let's say CPU or memory, so having a large buffer there is helpful.
Let's say the aforementioned VPS is suddenly under a lot of CPU load and legitimately can't keep up - Nginx can be trivially installed on it to load-balance between many downstream VPSes.
Now let's say you are running out of bandwidth. You may need to switch to a different connection with a different IP, change DNS records and wait for them to propagate, etc.
