Elon for example is worth 180 billion. His private jet, which costs $17k/yr to refill, is worth $62 million, or 0.03% of his net worth.
The average person, maybe lower middle class to middle class, is let's say worth about $250,000. If they bought or leased a car worth $45k, that would be 18% of their net worth.
It is probably the equivalent, or LESS than the equivalent of someone in the middle class, buying a candy bar. And they can do it over and over again with no repercussions.
And jet fuel is incredibly pollutant, and billionaires pollute millions of more times in general than the average person.
Liquidating is also stupid. That's not how they access their wealth. They take out loans, using their equity in companies as collateral. They don't sell off their stocks, because you have to pay taxes on that.
Realistically, people like Elon Musk have unlimited money. Some governments aren't even worth as much as him. He could buy governments and control people if he wants (which is what lobbying basically is).
If he wants to make more money he just has to pay the right people and do a little dance. Liquidation is in some cases completely irrelevant.
They are legends, they've painted super yachts, blocked private jets, and targeted golf courses to protest unnecessary emissions from the wealthy, which may as well be a paid-group by fossil fuel companies to divert attention from them being the biggest fucking problem.
Well I don't know if them gaining a conscience is realistic. But if doing the wrong thing becomes too costly and inconvenient they might stop doing those things. Well... they might do slightly less wrong things.
They can build fire retardant systems that are cheaper then golf courses and don’t involve wasting mega tons of water every month. Golf courses are incredibly wasteful and and unnecessary drain on our water supply.
