I don't think "create a viable competitor" automatically follows from "lower barriers to entry". Some ways to lower barriers to entry might be to eliminate tariffs, taxes, and regulations, or to implement a minimum guaranteed income. Of course, lowering only some tariffs, taxes, and regulations might well raise barriers to entry in some markets, as might an MGI. Interference in the marketplace never has only one effect.
