As with many detractors of anonymity, it seems that you're assuming that the authorities and neighbors you'll deal with will always be virtuous, and not corrupt nor vindictive toward opponents. Maybe you'd like to expose the town's government's corruption or mismanagement at the town hall, but the town is run by a family with a lot of influence and power over everything that happens within the town. You live in the town, fear for your safety, and have no good way of anonymously opposing their corruption, so you stay silent and they get to keep their power.

I don't see how these laws wouldn't make your identity public to someone, even if it's not the public at large. But it'd be enough for that someone to be an individual or entity who turns out to be interested in silencing your voice. Their knowledge of your identity would probably give them power to silence you not only on their platform but also on other platforms, if access to those other platforms is also tied to one single identity.

Bots are a problem but I suspect there are other ways of dealing with them, ways that don't involve making anonymity or pseudonymity impossible.
