You don't think anonymous speech should be protected?

    Voting?
    Reporting crimes in your neighborhood?
    Protesting an employer decision?

You can't think of any case where people would want their speech to be anonymous with just reason?

In the US voting is not guaranteed to be anonymous. It's protected and (mostly) un-traced to prevent coercion. But the fact you voted is recorded. If you live in a district with few enough voters (or voters who all vote the same way) your voting record could be used to tell who you voted for.

I don't think the other ones you mentioned are particularly compelling, no. There are ways to protect the names of people who report crimes without guaranteeing absolute anonymity.
