In Bruce Friedrich's new book, he writes, "Sometimes when I talk about cultivated meat someone will bring up the handful of states that have banned it. I'm mostly unconcerned. Cultivated meat companies won't be able to supply all 50 US states anytime soon anyway. Once there are multiple companies selling their products in...the majority of cities all across the country, the states that banned will-- I predict-- quietly repeal their laws" (p. 191).

It's hard to know how literally to interpret this apparently sanguine attitude, as the book is designed to generate enthusiasm for alternative proteins. But, still it seems raise an important question about the cost-effectiveness of repealing existing bans or preventing further ones. Initial thoughts:
 

• My guess is that he'd still view preventing additional bans as important, at least in key regions expected to be first-adopters. Maybe Florida and Texas would be laggards in adoption even if cultivated meat were legal.
• It'd be interesting to do an outside view analysis to see how quickly bans on other novel products have been undone once they've achieved a certain level of popularity elsewhere.
• He's writing as if the industry can definitely succeed in spite of the bans. But, even if the bans spread no further, they already apply to >140M potential consumers across the US and Europe. That, combined with uncertainty about the prospect of additional bans, may chill the sort of public and private investment necessary for industry success.
