To answer the question what possible benefits could come from total gun freedom, allow me to propose the following:

All the dumb, the illiterate, the suggestionable, the uneducated, the angry, the one’s in the 'right' groups, the opportunists, the extremists (in short: the Trump supporters) will be the first to jump on this new freedom.

The educated, the intelectuals, wil not because nothing good can come from this.

All that is needed now for the elite to take 100% control, is a sign from the Supreme Leader (the figurehead that the Elite has put forward to guide the riffraff and the opportunists), for the now fully armed canon fodder to overthrow Democracy, and install a single-Party government.

A revolution fully supported by Russia and China.

A new world-peace will emerge.

The world’s elite will be at peace, the people in submission. As God has willed it.
