Just producing more will kill Bricklink.
If you sort through used bulk or part out sets you will really make money only on about 5-10% of parts because they are not common.
All those parts 3-5 cents each are not profitable, bricklink sellers make barely minimal wage as it is.
Better solution for parts and pieces in my opinion will be to introduce smarter limits, maybe by lot total price or brick type.
If you are builder I can see the need of buying 200x bricks but not 200x deers or torsos.
