>#3 problem: banning a bunch of interesting uses. Can't transmit encrypted - linked to #1 and #2 I guess. As others have said, it's not generally a problem, and if there is something that requires confidentiality you're free to use another method e.g. phone, email, etc. But it's worth noting that not all cryptography is banned, just anything that obscures the contents of a transmission. For example, you can cryptographically sign messages to authenticate that they came from you. Similar to how you can use digital modes that aren't human-understandable (in the same way that morse or voice is) as long as the protocol specification is published somewhere such that it is possible someone could implement it from spec and decode the messages, or append checksums to your transmissions, etc. - as long as the content gets through in the clear it's OK.
