The point of ham radio in disasters is not for everyone to have a ham radio (that sounds like a disaster itself), but to have hams coordinate and forward communications. So they could, for example, sit at a community shelter and forward welfare messages to someplace that does have a sat phone (or long distance HF link) to send messages out of the area.

Though ham radios are no longer bulky nor expensive - I can hit a repeater 10 miles away from a handheld about as big as half a deck of cards with a 12" antenna.
