Complete Description of Additions/Changes:

If the lib directory does not exists, it is a sign of a bigger issue, not something we should expect. Kept the directory creation in client init and removed the logic checking for it in other places.

~~This was also part of the non-root enhancement (directory creation for those dirs in $HOME). Again, fine to remove, just keep in mind it might come up again one day.~~

Never mind, this is a different set of logic than I thought it was at first glance. These can be safely removed.
