Even in the US can buy guns over the internet.
Online gun purchases in the United States are very strictly monitored and regulated. It is not like any buffoon can order an AK-47 online. You need to authenticate your identity, and you need to prove that you don't have any criminal record.
Depends on where you live. In Pennsylvania, it is extremely easy. There are very few limitations on getting a gun or a permit to carry one.
Here are some of the regulations in Pennsylvania regarding gun ownership.
1. All handgun buyers in the state must undergo a PICS check at the point of sale.
2. License to Carry Firearms issued on a "shall-issue" basis.
3. Open-carry prohibited in the city of Philadelphia.
4. All private party transfers of handguns must be processed through a licensed dealer
As you can see, enough regulations are in place to prevent abuse of gun ownership.
Are private residences and private land that is inside the territorial borders of Pennsylvania, really in Pennsylvania?
The land and places that Pennsylvania has authority over are public lands. The people on their own private lands are not subject to these Pennsylvania laws.
The people may not know how to fight it in court if public officials try to accuse them of a crime on their own property. But if they knew how things worked, they could beat the State every time.
It's the same with smoking pot... in any State. If it is private property, and the pot is locked up so that a thief can't access it, the State has no authority. However, if the State usurps its authority, and the people are ignorant about how to fight it, the State will win, even though it acts illegally and criminally against the people within its territorial borders.
