"From this distant vantage point, the Earth might not seem of any particular interest. But for us, it's different. Consider again that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar", every "supreme leader", every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam. "
We can't keep our perfect home in working order after so little time but they believe we'll transform dead rocks with no atmospheres in paradise...

No paper plan dependent on "pulsed nuclear propulsion" ie blowing up nukes under your ass, is anything other than pop scifi.
"Pulsed nuclear propulsion" as Project Orion described itself is an insane pie in the sky imagined idea, and itself might not be possible, and yet Daedalus and Longshot both expect orders of magnitude improvements over that?
Oh, and the hundreds of tons of propellant for this magic drive has to be mined from jupiter or something.
Any billionaire pointing at space exploration as humanity's salvation is, IMO, either really just craving the attention and glory of conquest (much like Caesar, Napoleon, Alexander, etc) or seeking the conditions of the age of exploration (XV to XIX centuries), when companies were as powerful as governments and expansionism was unfettered.
Consider an alternate reality without food standards and regulations. Things like the melamine incident are commonplace and people regularly suffer due to contaminated food. Someone argues "perhaps the corporations should stop poisoning our food". Then someone else responds "Stop demonizing the executives, their objective is to make a profit, which they get from the consumers. The consumers are the ones buying the contaminated food, the executives aren't. If people don't want to get sick, they should exercise more diligence."
It's easy to offload coordination problems on the people who make imperfect decisions as a consequence, but saying "just don't have coordination problems, then" is rarely useful if one wants to mitigate those problems.
If billionaires were less greedy and paid more, more people could choose environmentally friendly options. If billionaires were less greedy and sold environmental options for cheaper, more people could choose environmentally friendly options. If billionaires cared about the planet, they could use their influence to pass laws for the good of the planet.
Instead you have corporations holding salaries down and squeezing margins from their customers. How's someone making the median salary in Bolivia ($3,631/yr) supposed to buy anything but the cheapest gas-burning car?
You got corporations going full cartoon villain too with disinformation campaigns, lies and bribes/lobbying to impede anything regulation that would cut into their profits. Exxon wants to keep selling gas, and the's a lot they can do (and have done) to keep you without any options but gas [1].
