That "capitalism" and "consumerism" are abstract concepts that represent pre-existing patterns of human activity that arise from a priori motivations, and are not things that exist as entities unto themselves exerting an influence on anyone's behavior or situational outcomes.

I've no issues with capital or people consuming stuff.

My issue would be with the corporations, which I see as the new estates. Except that they are far larger and far more powerful than what we had two centuries ago. Their perks include: regulatory capture, political access, access to finance. Ie powerful corporations run the infrastructure for capital movement and consumption - in their interests.
