> as the laws of thermodynamics simply do not permit for endless consumption of scarce physical resources
1) Ever-increasing consumption is not a prerequisite for capitalism, but rather a beneficial consequence of the increasingly efficient use of available resources which capitalism enables.
2) Economic growth is about increasing value, not physical materials. Value is a human concept, not a physical one, and can increase indefinitely unhampered by the laws of thermodynamics.
3) Copyright is anti-capitalist. It's a subsidy granted to one group at the expense of another in the form of a monopoly (or rather, many small monopolies) enforced through threat of violence. As a means of directing production toward "social" goals (encouraging the creation of "creative" works) instead of those chosen by the market it has its roots in socialism. Far from enabling further growth, it causes less efficient allocation of resources and in doing so impoverishes society.
