I agree we have limited resources. Those limited resources are our natural resources, not the artificial society created ones.
False dichotomy. Humans cannot do things collectively without an economy producing more than it needs. It also means our ability to do things collectively is limited by the productive capacity of the economy. Aggressive attempts to reduce CO2 would diminish the productive capacity of the economy and therefore limit our ability to adapt.
I didn't know you were a communist.
There is a huge range of views on government between communism and anarcho-capitalism. Saying that government is necessary does not mean government should be involved in everything. Incidentally, communist governments are examples of extremely incompetent governments that cause huge harm (e.g. Mao's great leap forward).
