Simple membership site: Laravel, or write your own?

I need to build a relatively simple membership site in PHP. It should maintain basic user info (Name, email address, etc.), control access based on membership status, and integrate Stripe payment system. That's about it. I think maybe I should learn and use Laravel framework to do this, but some people said to me that backend general purpose frameworks were bloated and I should learn to write everything from scratch. I hesitate to do that, though, because I want to make sure that the level of security is acceptable for what it is, and I feel like using an established framework is the way to go to ensure that it is already taken care of and I don't have to worry about it. Suggestions?
