I think the point the are trying to make can be justly summed with the following quote from the literature provided

“Whoever has accepted that liberation is necessary (at all) to end socially produced suffering and exploitation has no reason–other than an ideological one–to exclude animals from this endeavour. The analysis of capital relations as central relations of exploitation and domination in today’s society shows that the production of capitalist profits is not solely based upon the exploitation of wage labourers, but also upon the exploitation of animals (and nature in general.)”

It isn’t so much that artificially grown meat could not replace meat, but rather that as a part of our struggle for liberation we must logically include Animals. Indeed to think about it from a moralism perspective I now understand is to think of it from the wrong angle entirely. It is easy to mistake all vegans/animal liberation activists as adhering to idealist tendencies. The literature does a pretty good job distinguishing itself from this and providing a historical materialist perspective on the matter.

“The ecological damages caused by clearing rain forests, by monoculture cultivation or by the pollution of water are already partially irreversible. Therefore, whoever believes that they can ignore the production of meat or even transpose it into a socialist operation, is taken in by the naïve and romanticized image of industrialized food production that the capital lobby groups are promoting. The conversion of the food and meat industry into ecologically sustainable, vegan and socially planned production, in contrast, would be a timely socialist demand.”

Everything we do must be grounded in reality, lest we become dogmatic, idealist fools. It is no lie that the meat industry is responsible for massive damage to the earth. It’s abolition therefore is necessary for the preservation of our home planet. Artificially grown meat could not hope to replace it in the short or even medium term. There is no argument within the paper that necessitates the utter abandonment of that possibility, but I do think it is easy to understand the social change of vegan diets is clearly the better, more feasible solution. Alternatives to meat therefore would not likely by pursued by a wholly vegan society. That is to say if I woke up in the morning and the whole world was a United socialist project, it would necessarily be an important task of that project to convert the existing food industry into a, like the quote says, “ecologically sustainable, vegan, and socially planned” one.
