Are you implying that FRS users and Baofeng users are one and the same? This is definitely not true if so.
In my neighborhood as one example, FRS users purchase from one of the local or local chain stores, which carry Cobra, Midland, or Motorola radios.
Even if you purchase from Amazon, they changed their rules some time ago and require proper FCC certification on all radios. This means that you can't buy an FRS radio from Amazon which will let you do what you said. Even the Baofeng FRS units will come without the ability to go into ham bands.
And even then, if you managed to buy FRS radios without FCC certification, they come pre-programmed with FRS channels (so that they do what the label says they do) and would have to be programmed manually to use ham frequencies. I'm not sure which FRS users would or could realistically go through the trouble to do that, if any.
Sounds like you're thinking of non-FRS, non-FCC-licensed radios? Top Amazon results for "Baofeng FRS" here are the GT-22 and BF-88ST. Both are FCC certified, e.g. FCC ID 2AJGM-BF88ST. No VFO, UHF only. You turn it on and you're stuck on FRS freqs.
(It seems to me that the Baofeng danger-danger straw man gets larger by the day but it's still straw, and unfair given that licensing is done and specs are met.)
Like I said, the UV-5R isn't licensed or marketed as an FRS radio...this isn't a general Baofeng complain-a-thon, it's a thread that started with an unreasonable complaint that FRS users cause harmful interference on the ham bands. You hopped on with Baofeng tech specs, and I humored this, but now I have to say you've completely derailed the thread into nothing but Baofeng specs, a seemingly meaningless exercise given the thread contents. If this thread is going to continue for another week or two, could we at least get back into the proper context?
In fact it's extremely rare to find an FRS user with a radio like a UV-5R. Most of them are using Motorola Talkabouts, or Cobras, or Midland radios.
Another part of the reason for the lack of popularity is that people like to buy brand-name, popular radios that their friends recommend, and another part is that Baofeng does a better job advertising their FRS radios that are purpose-built for FRS. People shopping for an FRS radio like to buy something that says "FRS" on the box.
(The only person I ever met who used a Baofeng on FRS frequencies was a licensed GMRS user, and their use was 100% OK, of course)
