Every denial reduces the profitability and thus reduces the amount they’ll invest in data centres in the future

Your plan, if i understand it correctly, is hoping that if we deny them building a data centre here running off of renewables for ever increasing amounts of time... that they will at some point in the future have less money to invest in data centres and that will slow down emissions at some point in the future? The emissions that are stacking up now you're not bothered with?

“we don’t have to worry about our coal exports to other countries when accounting for our climate change impact. If we didn’t sell it to them, someone else would.”

That's because we're not the ones burning the coal, it's the countries we are shipping it to

In theory we can send a trillion tons of coal to indonesia, if they don't stick it in the microwave there's no co2 emissions

Which furthers what I'm saying, countries need to take responsibility for themselves, we Australians are burning trillions of tokens every year, we should be taking responsibility for our own emissions, not greenwashing ourselves and putting the co2 tab on America as you are doing
