You can put the onus where you want but I won't be the one spending tens of thousands of dollars on lawyers fees over the sale of $300 shotgun sold to someone on EE without due diligence. I'm no fan of the LGR but if you think that now that it is gone you don't have to do a verification, think again.
If I sell unrestricted guns on EE I will be doing a CFC verification, address, DOB and PAL verification. If that isn't amenable to folks out there, well then I guess that sale won't happen. I'd rather lose all the sales then be shelling out $50,000 to keep myself out of jail and try to recuperate my collection.
