This isnt inherently bad; its simply how n-of-n multisignature wallets work. Its analogous to a single-signature wallet where losing the single key is critical. However, with n-of-n, the requirement is to maintain all n private keys; losing even one means losing access to the funds.
If your priority is having a safety net or a backup plan for accessing your coins, then an n-of-n multisig setup is definitely not the best option.
