Your assumption are mainly coming from the fact that you do not own a BP yet and you are already starting to compare your snake to other animals such as birds or dog who needs human contact, socialization and stimulation my advice is research the animal you are about to acquire before rushing into buying an enclosure that might not be suitable for your animal.
YouTube is not the place where I would start my research when it comes to setting up proper environment for your snake, the highlighted part above just proves it.
You are getting a snake a BP in particular bare that in mind they are not social they tolerate being handled, handling is for your enjoyment not theirs, they need to be provided with security even if a cage is what you are set on remember that the enclosure needs to grow with your snake if you get a large enclosure and an hatching you will be doomed to have issues.
Again key word is RESEARCH and there are plenty of great stickies on this forum that will help you provide your animal optimum husbandry which will lead to a successful first time owner experience.
