I'm sure most planets has a "home fleet" either home built ships, or older starfleet ships.
Each planet/government has there own agendas when it comes to space travel, sure some go to starfleet. But a planets government agenda may be different to what starfleet does/wants to do.
A planet like vulcan may be a bit zenophobic, or like some members of the federation, there life support standards aren't compatable with "Earth standard" Higher heat, greater presure, aquatic, etc. So some intrepid people may live an uncomfortable life to be in starfleet, but most would serve on a home fleet ship.
A planet may be looking for colony worlds, but starfleet may not have any ships available for years, or back burner. They may want to explore everything themselves, instead of the information being given to them.
Imagine, we finally get out into space, we want to go explore, but a "Federation" shows up and says Hi, we've been around for centuries, explored the 1000s of light years around, here's the the data. Well, okay, that would be deflating. We get all hopped up, want to explore alpha centauri, some aliens come by and say, meh, just a rock, no life, here's the data..
