Thank you @rjs for your helpful reply.
What confuses me is the wiggle room / discretion available.
For example, if someone visits NYC or Boston for a few weeks and works out of a hotel or Airbnb, they typically aren't going to file a tax return for those states just because of that visit, especially if their employer isn't doing that withholding actively.
If that's the case, couldn't one extend that logic to any other state one is a digital nomad in?
In my case, I was visiting...it just ended up being a really really long visit...so I'm wondering if there's any wiggle room here at all.
