It's not a judgement on he meaning of your life it's a judgement on the authenticity of your life and the accuracy of your view of the world.

Which view point is better -- one that believes in a flat earth or one that sees the world as spherical and all that this fact entails?

A flat Earther can't put a rover on Mars but someone who knows that the world is round can.

Imagine what a person who comes to understand that the world is a simulation could do.

What you're really arguing for is a deeper understanding of the universe. Whether the universe is a simulation or not is irrelevant.
