This post sounds to me like sour grapes. "I can't go, so I don't want anybody to go unless we all can." I hope I'm wrong, because that idea terrifies me a bit.
Its not sour grapes. When Neil Armstrong went to the moon it was for all Americans and all of Humanity. During the space shuttle missions there was a public effort to try to select a broad representation of cultures, backgrounds, educations, nationalities etc to be astronauts.
However, if the only ultra rich get to go, which it sounds like the case since that would be the only way to fund a private mission, why should everyone left be ok with it? Why should the richest people in the world, most who have had a incredibly large role in environmentally destroying the ONLY planet all of humanity can live on, just leave everyone else to clean up the mess? It would be the ultimate FU to the rest of the 99.9% of humanity.

Oy vey... that might be a sentiment which befits an established enterprise, but it is no way to reach for the stars.
Do you think Magellan or Columbus tried to be inclusive when they were looking to crew their expeditions? Of course not, they selected on whatever capabilities or vices they deemed necessary for their purpose. Did the Vikings go for a multicultural crew when they tried to reach Vinland? Nope. What about Genghis Khan, did he choose his troops by looking at the colour of their skin or their cultural heritage? He probably did, the criteria being 'just as long as they look and talk like me'.
Trying to be culturally sensitive and inclusive might work when trips to Mars are organised by the UN, based on technology and experience from pioneers like the current crop of 'commercial space access providers'. This is not where we are just now, however. Right now the selection criteria are altogether more practical: can you afford it, cope with the stress, have the right capabilities, can you function as a crew in a cramped environment for an extended period, can you handle the possibility of being left 'stranded' on a planet hostile to (our) life?

Now, if all was fine and dandy on Earth and some rich people want to take the risk of starting a Mars colony with the idea that most of us will be able to travel back and forth in a hundred years go for it.
The problem is, there is an asteroid on a collision course with Earth. Oh, and the asteroid was created with help from some of the people trying to now escape. The asteroid is global warming. I can go into great detail on how global warming is going to make things incredibly challenging for the 9+ billion of us around on Earth in 2050. At least to Elon's credit he's doing some things that might make living in a warmer world a little more sustainable before he jets off to Mars. Most people that will be able to pay the price won't be doing so.
Wouldn't be more ethical to focus on saving the one planet most of us and our kids will live on? Lets say the Mars colony is successful. So successful that you and your families chances of surviving are actually better on Mars vs Earth. What gives you and your offspring the right for that greater chance of survival? Because you are rich? What about executive XYZ who lead company ABC for 20 years and used our air and water as a dumping ground for pollution. What gives them the right to leave? What gives them and their offspring the right to survive and thrive on another planet while us on earth deal with the cost of that pollution. As I said, it would be the ultimate FU to 99.9% of us.
I think a spaceship designed for and by those who have the means and will to design such will work just as well for those who lack either, or both [1].

You are missing the point. Capital funded the moon missions as well - just in that case it was the capital of the community you belong to, let's say your nation, so you feel involved. Nowadays NASA can't even put a human being into orbit any more - and that's not the fault of SpaceX.
As a "public Common", everybody should be allowed to go there. That's not the same as to claim ownership, which indeed should be publicly and very well regulated.
