No, you can own a car, boat, without registering it, you must register your car to drive it on the roadway, driving is a privilege.
I do not have to ask permission from government to buy a car, a boat or a gun, owning a gun is a right, not a privilege, you want to turn my right into a privilege and take that right away from me.
You want me to be helpless so you can use political violence to dictate how I live my life.
You will not take what you want from me, my rights, my Freedom, as long as I draw breath.
Note: We do have to pay property tax on real estate, forever or it will be taken away if we don't pay, this is a perfect example why we will never register our guns which we have a Constitutional right to keep and bear.

"UBCs would be effective going forward without anyone needing to register any that they owned prior"
BULLSHIT! A UBC scheme would be a pathway to registration, because it would fail without registration.

It is a God give right to keep and bear arms and it will be defended as such.
