There might not be much of a market for it. Vegetarians and vegans are used to industrially processed protein substitutes but most of them don't really want meat and its flavor. In contrast, many non-vegetarians want natural high-quality products from real animals, they don't want to eat industrially processed lab meat. A market would have been low-cost ultra-processed meat products but for that it seems that lab grown meat is too expensive.
This can still change though, if the products of animal farming were to become more expensive and with higher mandatory quality standards, as they in my opinion should be.
