Not true at all. UK was doing >1million rapid tests a day when schools were open. They will do that again when they are back from easter break.
Also, the false negative rate isn't a big problem IMO. The PCR 'false negative' rate is far far higher because we are only doing a few hundred thousand a day, so 90% of people are getting missed entirely. I'd rather a 50% false negative rate than a 89% false negative rate from PCR.
There is also the problem that PCR takes at least a day to turn around as well - which will result in more spread.
I'm not saying we should get rid of PCR testing and just do LFD but doing both is probably the best option.
