How is that harassment if people calling me about student loans I don't have isn't harassment?

Intent.

So intent to be annoying is a worse offense than intent to rob someone?

"Hi, I'm calling to ask for donations to our 'Stop Robocalls' lobbying effort." If you set up a nonprofit org., and did that, then you would probably get past a lot of roadblocks, and might actually make some money.

If this is true you could just robo call them with the intent to sell them something, or looking for someone. The annoyance part is merely a side effect vs. the whole purpose (at-least it could be argued that’s the case)

Robocall to ask them to donate to your gofundme which you will donate to the election campaign whoever proposes an anti-robocalling law that meets X, Y, Z, criteria and is actually signed into law.

Convince some industry group to seed it with $20k or so, target a small state where campaign donation amounts are low and bam, you've got your first anti-robocalling law (with teeth) on the books.

To which one’s defense should be, “I did not do this, my corporation did. Arrest it.”
