FWIW I think repealing the symbol rate restrictions and opening up bands a bit more would go a long way towards the spirit that ham was started with. The hobby seems pretty ossified these days and it would be great to see more advancements in digital modes and stuff closer to the state of the art.
Re disaster support: complete and utter LARP to an embarrassing degree. I've been familiar with a variety of clubs all my life through participating family members and this simply doesn't happen in a way that has any practical benefit to anyone. Again, opening it up would improve disaster comms quality by incentivizing development of better protocols and by getting access to those methods out of the hands of the unqualified gatekeepers of clubs.
