Because it's Yet Another Step in the wrong direction, and will be used as justification down the line to get rid of AM/Radio/Analog Radio a bit more or entirely. Keeping it around, or in a car, may be the wrong or inefficient way of solving the problem of comms in an emergency. But it does mean that we "force" the lingering of the tech in some way, so as to not let it be dismantled in the relentless march of whatever is causing these kinds of things to disappear.
It's a quirk or random fact of history that they got put into cars but not houses, but that doesn't mean we should get rid of it. It's smart and reasoning people like you and me that look at this and think "ugh, no need to have it in a car, we can have it in a bug out bag and it'll make cars cheaper, etc". But that kind of thinking is wrong for society past a certain point.
Before we know it, we'll own nothing, we'll rely on Daddy Government for everything, and we'll be happy! Maybe they'll let us own a Digital Government-Issued Codec-Infused Satellite Radio®, so they can reach us at all times.
These people act as those cost analysis doesn't exist. It costs close to nothing to provide a radio, but the benefits can be huge.
Our government should step in when it makes sense. We determine if it makes sense via cost analysis and risk analysis. This is why the communism slippery slope argument doesn't work.
For example, banning public smoking along with other measures have saved millions of lives in the long run. Of course smoking is a personal choice, but it's also addictive and dangerous. It is sometimes beneficial to override people's "personal choice" if the benefit is big enough and the cost low enough. Ultimately, pretty much everyone is now grateful public smoking is gone.
