@freemo @admitsWrongIfProven I don't agree. We're taxed plenty. Giving government more chances to shake people down doesn't sound great to me. Next they'll say I didn't charge enough because they didn't get as much tax as they'd like (this happens with private car sales).
why does the state need a cut if I'm not making a profit? I think there are often laws setting boundaries for what qualifies as a private sale. A person manufacturing weapons for sale must register with the government and add serial numbers so it's not like allowing private sale allows me to print and sell fgc-9 over and over or something. In fact if I had one I think it would be excluded from private sale allowance because it's homemade anyway. I also can't rent hours on my printer to someone who wants to make one. I can't even let you use my drill press for an 80% build. There is lots of regulation in place around private sale/trade/manufacture already.
