Labelling of GMO food is an example of a requirement based on public concern, where that concern is not supported by scientific evidence of health effects.
You are implying the consumer concern is entirely about health effects. It isnt entirely.
I'm implying (now saying directly) that consumers in general, lack understanding of the topic. Most don't make use of reliable information that is readily available and base their understanding on over-simplified and/or skewed sound bytes.
GMO food has been in widespread use in commercial crops since the 1960s. Most modern crop varieties were developed by the deliberate genetic mutation of plant material, using for example radiation and/or toxins.
The notion that genetic boundaries between species are stable in the absence of GMO is simply not true. DNA is continually being copied and pasted between species via natural processes.
Something like 10% of the human genome is currently understood to be exogenous DNA.
