Nothing theoretical about it.

Edit. Here specifically on decoupling:

CO2 is totally diffuse in atmosphere and the climate change is global. Outsourcing pollution has no effect on this issue. And the fact is, global CO2 emissions are at an all time high year after year.

“Taken as a collective, developed countries are found to be outsourcing emissions to developed economies; however, this is largely due to the U.S. and China”

It has the effect that it makes it worse, because goods have to travel longer distances.
Note: I'm not entirely convinced economic growth depends on population growth, but historically that has been the case in most countries that haven't exhausted their windfall natural resources like oil and have healthy export markets.
There's a limit to the physical quantity of non-virtual goods you can eat, as well. If you switch from eating a $3 burger to a $100 steak with the same nutritional content, that contributes to economic growth with no change in resource consumption.
Plus, the $100 steak is more environmentally expensive too, even if lab grown.
There are signs that the energy-lite economy growing isn't as useful to people as the old energy-connected one.
Having a country offer their own currency as the global reserve currency was stupid to begin with. It's no surprise that it will have to end one day.
You can do whatever you want to entropy if you ignore stuff going on to a connected external system.
"It is logically possible to have increasing GDP and a decreasing physical and energy throughput in an economy. However, it is a fallacy to move from claims about what is logically possible to claims about what is physically possible and another from what is physically possible to what is empirically actual."
If you actually look at the coupling of environmental pressure with historical empirical economic growth measured by GDP, we can't go on like this for even a few decades more, if we want to avoid complete ecological collapse. Trusting humankind's future on theoretical armchair economics magically becoming a reality, despite decades of evidence to the contrary, is complete madness.
