Think you have a lib of smart contracts like you have a lib of java code. Part of your code is used internally and you have an authz server (typically not the one that runs the java code, in MS world it's active directory). Think that you have dockerized your java servers. It's not that you don't trust your employee laptops for development, it's just that you want to reduce the differences between dev and prod. Same for blockchains, you want a lib of contracts, you want authz, you want to reduce the diff between public and private.
