That's not insane, that's pretty cheap. If you buy IPv4 addresses in bulk (e.g. an entire /18 or so), they're ~$40 a piece these days.
When you buy cloud services from AWS or GCE, you're still paying for those IPv4 addresses, it's just baked into the price. Hetzner makes paying for it optional, which makes it so much more visible.
