There is nothing this can do that a normal microcontroller can’t do. banning this device does nothing to harm penetration testing. it just mitigates the ease with which these exploits can be widely abused.
That's kind of the point though - the more widespread you see it being used the more likely it is that the tool itself will get more attention and the targets of the tool will get more attention. The point of a bill like this is to show the population that politicians are doing something, and trying to avoid nation/global news covering the topic.
For another example of similar politician behavior just look at how LA is handling the graffiti towers. They're driven by concern about being on the national stage and the corruption of the whole system being put on display, not about the graffiti.
