There is too much fantasy about distant habitable planet and not enough about making a planet in solar system habitable or building artificial habitats

The second is likely easier than the first

Not just likely easier. Far easier. They're so far apart on any reasonable effort scale that the comparison is basically meaningless.

Or even before that, fixing the habitat of the planet we are living on. A lot of the current cultural fantasy of colonizing space feels less like expanding the human frontier and more like escapism.
