> The economic system itself is incompatible with the physical reality of a finite planet.

„Infinite growth is impossible on planet with finite resources” is nice buzzphrase, but upon closer inspection it makes literally zero sense. Fortunately people will never accept degrowthers’ postulates.

[uv-depression]

You're making a very strong claim ("literally zero sense"), but you've provided no argument as to why. I don't believe that the economy can become arbitrarily decoupled from physical goods, which is a hard requirement for infinite growth with finite resources.

Because 1) growth is not directly linked to resources and the richer country is the less growth depends on resource-intensive areas such as farming or industry; 2) it’s absurd to think we are at the stage of growth where resource availability becomes constraint - I’d say it’s on the contrary and we are at the stage where we become far less dependent on resources than are on scarcer side (e.g. thanks to solar uptake).

[uv-depression]

But the claim must be that physical goods can become an arbitrarily small portion of the economy. Nobody would dispute that they've become smaller. Do you believe that food can become arbitrarily cheap relative to total wealth? Or steel, or silicon? In other words, can the food you eat require an arbitrarily small portion of your income? And looking at nation-states only is an accounting trick; the economy is global.

You again say "it's absurd" and provide no argument. I think the case is not as clear cut as you would like it to be. Solar energy is not an infinite resource.

Yes, if you actually mean infinite growth it’s true. And that’s what I find absurd - why would you care about infinite growth? If you actually care about infinity, then even if you degrowth you will run out of resources because guess what - resources are finite, so the use of resources will have to also be arbitrarily small and asymptotically approach zero!

[uv-depression]

What? Some resources are renewable. There's a finite amount of solar energy, but it doesn't "run out" (on human timescales). Growing food doesn't need to remove from the biosphere, even if the way we do it now does do significant damage. So we absolutely must stop using non-renewable resources (i.e. fossil fuels), but if we find an amount of renewable ones combined with recyclable non-renewables (like metal) that are sustainable then we can reach a steady state.

An economic system based on perpetual growth can never reach a steady state, unless you believe that physical goods can become an arbitrarily small portion of the economy.

[azan_]

You can’t reach steady state in ANY economic system because you can’t have 100% efficiency, that’s basic thermodynamics. Resources will keep decreasing no matter what you do. Hence argument about infinite growth is absurd - infinite existence without growth (or with degrowth) is also impossible.

It appears that they believe you can eat emails (according to the substitutability principle).

[azan_]

It appears that parent comment believes that there’s infinite amount of food and once you degrowth you will never run out of it.
