Letter: Why do people want to ‘keep their coverage’?

I don’t understand why such a big deal is made of whether people can “keep their insurance coverage” or not. Who cares?As long as my coverage is good and it's not a hassle to use it, what difference does it make who provides it? I've had my same insurer for years now, and if I got a new one tomorrow with the same premiums and benefits, I wouldn't spend a minute more thinking about it.If Medicare for All provides equivalent benefits and I'll pay less overall, then I'm all for it
