I get being sceptical. But "a different food technology turned out to be harmful so this one must be the same" - that's a bad argument.
The argument is that we're taking a major public health risk on the basis of low-quality science, in an industry with a questionable track-record.
This isn't just a new food product. This is more directly comparable to a new pharmacological compound, and ought to be treated as such.
Are we? (I really don't know the answer to this.) What's the science behind it and what are the gaps in it? This is the first time lab-grown meat is being sold and so far it's happening only in one country on the planet.
An argument would be evidence for this claim about "low-quality science".
