Sure, let’s treat guns like cars -
Mufflers are mandatory.
No legal limit to how many cylinders, or powerful they can be; you can own cars much more powerful than police cars.
Driver’s license is good in all 50 states, including NYC and Washington DC. It’s even legal to own *trucks*.
No background check for purchase or sale.
No age limits for purchase.
You can own as many as you want, and you can buy as many as you can afford.
You can buy cars in any state, and have them shipped to you
You can build cars from scratch in your garage - yes, the dreaded GHOST CARS
There’s no need to ever register any cars you don’t drive on public roads.
Fully automatic transmissions are legal.
You can take your car to school. Every day. No questions asked.
Are you really sure you want to treat guns like cars?
That’s a great retort.
