Loving yourself is natural, Ephesians 5:
For no one ever hated his own flesh, but nourishes and cherishes it, just as Christ does the church.

In James 2:8, is it assumed that we love ourselves?
Yes, but not in the selfish loving sense.
Here another verse that makes the same assumption, Ephesians 5:33a

We can only give to others what we have possessed. If we do not love ourselves, we have no love to give. If we only love ourselves, we do not know love, 1 John 4:7
Beloved, let us love one another, for love is from God, and whoever loves has been born of God and knows God.
