If it’s not unconstitutional it should be. 1000% tax is an effective ban. Until they stack SCOTUS we might have a chance striking it down, if it gets passed.
The SC hasn't bothered to even hear one of the many possible court cases on state AW bans over years. None of these have been overturned (permanently) by lower courts.
We will see soon if Amy Barrett is going to make any difference. John Roberts would vote against us for sure.
Given how pathetic the court has been on guns for a decade, I don't think they are going to overturn any of the bans or licensing schemes. Nothing the court has done has had any effect on the large majority of the USA. It has only effected the extreme outliers (Washington DC). The current case we are waiting on will presumably only effect the small number of states with may-issue CCW.
If these states are forced to go shall issue, they will probably just make it obsecenely difficult and expensive to get a permit, and stack on banned locations... and every court will think that is just fine.
