no, you're confusing (and trying to redefine) basic economic concepts that are generally well-understood and well-defined by economists (particularly you're conflating profits with rents[0]).
by definition, profits are rewards for productive use of capital, while rent is the income gained from simply having capital.
some lazy and greedy market participants (e.g., plutocrats) contrive to rent-seek, but capitalism (and economics in general) considers such a misallocation of resources the worst kind of economic sin. so yes, there is something wrong with that.
capitalism expects such situations to be short-lived, as compeition drives such profits to zero. if that doesn't happen, then the market is distorted (by some expression of power).
