Here's a question: What happens if you refuse to pay to be put in the database?
You will not be able to proceed to step 2 You will not pass GO. You will not get any "permit" to exercise your Constitutionally-guaranteed right. You will not legally possess a firearm. Their (our "public servants") rules.
They can't legally deny you the ability to exercise your constitutional rights because you refuse to pay a fee.
You're kidding, right? Did you refuse to pay the fee to have your fingerprints taken and entered into the NICS database? If you refused, you have no legally registered firearms in Hawaii. Next year after they mandate firearm liability insurance and/or required psych evaluations (or any other thinly-veiled confiscatory infringing "fuck you" bullshit), if you don't pay for and have proof of those, you'll not be allowed to exercise your rights as (supposedly, but obviously not) protected by the Constitution.
If they refuse to allow you to register your firearms the fault is still theirs for the same reason.
If you walk in with a firearm to register, and refuse to complete the required process, you will shortly be visited by agents of the government who will, at gunpoint (theirs), forcefully confiscate your ("illegal") property.
So what are they going to do? Put you in jail? Tell your mom?
They'll do whatever they can to make your life miserable, and they are not short of personnel or (taxpayer supplied) money (at least when it comes to enforcing the "common sense gun safety regulations")..
