CMV: Lab Grown Meat Is A Good Option For Vegans

The Japanese have demonstrated the viability of lab grown meats recently, replicating the taste and texture of steak from nutrients supplied to cultured flesh.

With the acceptance of meatless products like the faux sausage in Starbucks meatless breakfast sandwich and BurgerKings Impossible burger, meatatarians have shown a willingness to accept that as long as the product satisfies their requirements for taste and texture they will buy it.

It seems equally reasonable that vegans would find a sustainable lab grown product would be acceptable particularly as they often state that  they enjoy the taste of some meat products but that they abstain for moral reasons.  Given that both hydroponic vegetables, fruits, and now  lab cultured meats are grown from raw (non-animal) sources, perhaps vegans and vegetarians can reintroduce a tasty food source rich in B12 back into their diet.

Edit: I confess to not really understanding what Deltas are and what to do with/about them.  If someone would be so kind as to explain, there are folks here raising really good points but I don’t know if that applies to this sub or how (colour me embarrassed)

Edit2: The B12 observation was an aside (and I will admit to a small crass attempt at marketing my position.). I realize that B12 is available in numerous ways.  Ignore the comment please as it is completely peripheral to the ethical issue behind this CMV.

Not all vegans enjoy the taste of meat. I, for one, have nightmares about eating meat.
Lab grown meat can still have much higher energy or water costs in comparison to vegetables and pulses, so for environmental/moral reasons, many will still abstain from lab grown meat.
