A believer has hope and the nonbeliever has none?
Or... it is better to have no or little hope than to “foolishly” and “naively” have hope?
Faith = hope.
Not everyone has faith. Faith is a gift from God and not everyone is so fortunate to have it offered to him by God.
Jesus promised His disciples that in this life people would "revile you and persecute you and say all manner of evil against you, falsely, for My sake" and that we would have a "cross to bear," and that we might end up fined, imprisoned, beaten, bankrupted or dead, for our fidelity to Him.
Our hope is not for prosperity, comfort and ease in this life, but for union with Him who loved us, in this life and the next.
