(gosh, if only there was a technology that could perform Network Address Translation.... oh, no, sorry, some fools condemned all that because "IPv6 would fix it all"... all that stuff that's not actually broke...)
Wrong. IPv6 NAT exists, and is as easy as IPv4 NAT.
Just because some "fools" say you no longer need to NAT, you can if you want. Heck, there is also DHCP6 and IPv6 private-lan address ranges if you really want to stay old school and stick with ip4 type restrictions.
Please don't make stuff up to suit your argument, or call people fools because they understand the headaches NAT can cause. It makes you sound like Trump.
