I can build an app in a weekend but forming the company behind it still takes weeks (I will not promote)

Genuine question, you can vibe code an entire product in a weekend, deploy it the same day, get users within a week and ai handles the code the design the copy the support but when it comes to forming a business entity and opening a bank account im still filling out forms on government websites and waiting for bank approvals like its 2005. The building side has completely changed but the business setup side hasnt moved at all. Am I missing something or is this just stuck in the past, what are people doing t
