If you intend to practice the hobby, get the license. I let mine lapse after 10 years because I don’t practice anymore, but I generally still remember the basic rules and how to operate the gear, so if I ever had an emergency need I’d use what I had access to - but I haven’t transmitted anything in years and years.
And intent is functionally impossible to prove, but endlessly arguable and a judge can make a finding based on their judgement - something very different from proof.
Correct.
