Unfortunately, that kind of thought process is how you end up with dozens of vulnerable devices connected to a hospital intranet. Everything works fine as long as nobody tries anything fishy, but all you need is one device with a buggy Bluetooth implementation to bring down the whole house of cards and kill a bunch of people.

Apologies for my denseness, but how could buggy Bluetooth bring everything down?

I vaguely recall something about a faulty hospital device with Bluetooth or Wi-Fi being posted here a little while ago, but I'm not certain.

Buggy means vulnerable in this context. A vulnerability in the Bluetooth or Wi-Fi stack is a good way for someone to compromise a machine remotely.

Once you compromise one machine, you're inside the firewall and in a much better position to exploit vulnerabilities in other machines in the network.
