Bear in mind matter isn't the only component. Energy is another huge input to the system. E.g. blockchain and its derivatives use tiny amounts of matter to use enormous amounts of energy.

We can and must develop more environmentally responsible sources of matter and energy. Trying to change human behavior with our current regulatory controls have been demonstrably inadequate. There are sources of matter and energy that do not run out, I believe them to be in space.
