If you have a monetized Youtube or facebook account, You must have someone who will takeover the account when you die because even if you stop uploading. It can still make money from royalties. Or they can continue your channel.
For non monetary reasons, The purposes of letting another person takeover your account if you die is to preserve your posts like the pictures of blogs. Some dead celebrities still have active social media accounts. When WWE wrestler Chyna died, her mother took over her account. She uses the account to sell her merch or make conventions for fans.
An Aunt of mine who died dont have monetized social media accounts but her children took over her account to keep her pictures safe.
