You provide a good example of this sort of rationalisation: the benefit to the individual is highlighted, the collective harm is ignored.

That seems like a somewhat random point to make. Sure, there are positive characteristics of meat - just like there are of bitcoin. That's part of why the comparison between the two works.

In terms of conversation you got a point yourself, however you cannot compare food with currency. Food is connected to us on a biological level, currency is a construct of society.

They are not compareable imo.

I'm not seeing what is about food being "connected to us on a biological level" that makes the comparison fail.

Not all aspects of two things have to be similar in order for a comparison to succeed (such a comparison is of course actually impossible).
