You'll need to spend more time using VRChat before you can upload avatars or worlds. We do this to better understand ourselves and for security reasons.
We'll let you know by email and in VRChat when you have the option to upload. You can study and test right now using your own equipment.
Not everyone will spend a lot of time playing or be overly social, but only those who do will receive the benefits that helped VRChat become as popular as it is today.
To get his avatar and be able to fully experience the game, I'm not going to be able to persuade my friend to hang out for more than 24 hours and mingle with everyone else. It's just a real drag on every new player to try to fix a problem that could be solved in other ways, and I have a feeling that there are thousands of others in the same situation.
