It's really about the way the game is intended. There will be a lot of balance iterations on the economy side but if you really want one of the bigger ships, you're kind of going to need a team of people. Like on the Enterprise, you've got Kirk and Spock etc. Running some of the larger ships will cost significant resources and you'll need people to contribute to that. Missiles will of course also cost. Right now, if your ship blows up, so what, in the future though it will carry real consequences. People are really going to need to work together to figure this stuff out and fund it.
