Yes, that's the Musk perspective. But he's wrong.
What we need on Mars is robotic mini factories, hundreds of them. Actual industrial infrastructure. Not people. People can come later, after all the parts and pieces are in place.
Advocacy of the same mistake we made with the Moon for Mars does not create a space faring people.
I disagree, we should start off with a simple unicorn ranching operation then move on from there.
