Meaning, what? About .0001% of the population?
Meaning the next time your town is hit by a hurricane, tornado, earthquake, flood, etc. the 100% of the population depending on the guy down the street who used to be involved in ham/emergency communications will be stuck.
That guy gave up his hobby after being wiped out by interference. The fact the the interference is gone during the emergency, and corresponding power outage is irrelevant. He got rid of his gear already. So sorry, no comms.
By a rough estimate, your guess is at least three orders of magnitude too small.
"Meaning, what? About .0001% of the population?"
That .0001 percent might save your bacon in the event of a severe disaster.
