Thinking more........if Ohio gets it passed with the oligopoly controlling grows, it still gets us closer to the time when the surrounding states (Mich, Pa, WV, Ky, Ind) will almost have to follow suit and legalize as well. When that happens, the oligopoly's leverage crashes and the market retail prices are more regionally influenced.
Of course, this depends on the neighboring states falling into line, which hasn't exactly been the case in the states adjacent to Colorado. I think of the five states contiguous to Ohio, only Michigan is even considering legalization and then only at the local levels.
