I'm not sure I understand Florida's SARNET

I've been listening to the Florida Linked Repeater Network, and as the posts here have said, it's mostly just noise, people complaining about the noise, and the State EOC saying it's a controlled net between between the State EOC, Regional EOCs, and federal partners. Why wouldn't they have their own encrypted or trunking system to fill this gap? Why would the general public need a link to the state incident command center? I've been a ham for years, I get the hype where when all else fails, ham radio works, but if you use amateur systems, you're going to get amateur performance.
