**** with 'em. Court said they can't pass that law. That hasn't changed.
Some laws just plain require noncompliance.
I'm not going to be one to tell you what to do but I will say the federal court appellate case that overturned the original drone registration law has been superseded by a Congressional bill that was signed into national law by the President. The applicable registration requirement is part of the new National Defense Authorization Act for 2018.
H.R.2810 - 115th Congress (2017-2018): National Defense Authorization Act for Fiscal Year 2018
Understand the justification for the appellate court win was a clause in Part 336 that stated the
FAA shall make no law that would directly impact model aircraft. Part 336
did not say that Congress shall make no law. The purpose of Congress is to make law, which they most certainly did with the new bill, which became part of our code of federal regulations when the President signed it.
The AMA was very supportive of re-instating drone registration and provides a few answers to FAQ's on their website
Academy of Model Aeronautics - FAA UAS Frequently Asked Questions
The AMA seems to suggest people use their AMA numbers to supplant FAA registration numbers on their aircraft. Bear in mind there is nothing in the law that provides for replacing the FAA number with an AMA number. if you were cited for anything through the use of sUAS and were using only your AMA number for air vehicle identification you would likely be found in violation by the FAA and/or NTSB and subject to a civil penalty. We should also understand that the AMA is not named as THE nationally recognized community based organization, and that the AMA has absolutely zero regulatory or enforcement authority over
anything.
The AOPA has also been supportive of drone registration but if enough multirotor operators were to join the AOPA there could be far more people that fly sUAS than people flying full scale in the organization which would help leverage political lobbying more in our favor. Go here for the AOPA view of the new law.

There's another law being considered that every one of us should be very concerned with related to UAS drone tracking:
http://www.aero-news.net/index.cfm?do=main.textpost&id=06879114-edef-463b-b9bb-b7ca26ca75e2
It's essential that we come together to let our government know drone tracking is something hobbyists neither need or want. Big aerospace does because it will help clear the skies of our stuff and make it easier to incorporate their equipment, equipment that will put small commercial drone operators out of business through excessive, burdensome training and equipment requirements and certification processes. The cost of tracking technology will in one way or another impact us all, and likely reduce or already limited flight time through increased loads on our batteries by adding weight and signal transmissions. If the government was to adopt any given manufacturer's hardware or software for identification transmission every other manufacturer would have to pay a licensing fee to the developer of the hardware/software which would in essence give the developer a monopoly on multirotor development and distribution. It would also give the developer authority to collect and maintain your personal and operational data, something DJI already does.
As things currently stand, if you register your aircraft for warranty purposes with a manufacturer the government already has a starting point to look for people. If you have a DJI system that becomes even easier for the government as DJI (although they deny it) receives your flight data via automatic reports from their GO App and during firmware updates, and will instantly provide it to a government agency. This has already happened with the incident between the Phantom and Blackhawk. The owner of the Phantom was found because of flight data collected and provided by DJI.
Again, I'm not going to suggest anyone register with the FAA. The maximum fine is only $200k. I don't have anything like that to spare, but some of you are likely much better off financially than I am.
