  1. Why is it important to encrypt your wallet?

    tl;dr --> Protect your ASS-ets!

     If a wallet is NOT encrypted, then anyone who gains access to the wallet

    will basically gain access to the data the wallet contains -

    both the ‘valuable’ actual bitcoin hash data, as well as the encryption key(s) data -

    and this will then give that party the ability to do whatever they wish, with that data -
    including steal-spend it, hack-destroy it, etc.

  2. What is the risk of not having a password if an attacker gets access to your file system?

     A pw can be considered a subset of the class of encryption,

    so the same arguments apply as in the 1st question above.
