5. Oh yeah... we can also beam anywhere in the galaxy now apparently... why do we need ships anymore?
To quote myself from another thread
Because transporters don't help you keep the balance or fight off the Klingons, Romulans or whoever else, when they come for you with their fleet.
And because you need starships and their facilities to explore unknown regions of space. You can't keep beaming people blindly hoping to hit a habitable planet.
