Today I was reading some opinions of people who believe that there is
no reason for humans to leave earth. Are all arguments for moving into
space and onto other bodies in space really that weak and irrelevant?

To say on the one hand that there is no reason and on the other 'it is too
expensive' is a kind of a contradiction. This means that if it was a lot
cheaper then it would be justified, and that means there must be some reason
for doing it, and the persons putting forward such an argument obviously
recognise that. So if it just a question of allocation of resources, rather
than fundamental value of the enterprise, then fine, it should recognised as
a financial discussion, not really a philosophical one.
