The long bolts are NLA for good reason, they can bend or even worse snap off making removal near impossible.

My 91 300SL parts car had very stuck long bolts, a few bent while taking them off. One way to help things along is to hammer on the end of the bolt, this compresses the ball seat and relieves some of the tension. It is up to you to protect the wheel and lug. ( Placing a socket on the bolt then hammering on it or perhaps a extension. ) The wheels on the parts car were all bent so I just hammered away.

Ball taper lugs can get very stuck even at low torque levels.

As for the person that was using a 1/2 to 3/8 drive adaptor, that is just asking to break the tool.
