"And to be completely honest, it’s just not enough. I believe that working with a team of people that are more experienced and smarter than yourself is crucial for your development, and as a freelancer, doing minor gigs involving some MVC/CRUD application programming, you just miss out on a world of possibilities to grow and learn."

I've experienced this as well, it was my main grief with working by myself and on the road and ultimately led me to join a company again part time. Sadly the team I joined isn't really what I expected from a team, so I'm already on the lookout again :(
