I agree that the present restrictions and taxes on suppressors are ridiculous, but we should be careful on how we present this argument. Using the argument that the noise from unsuppressed firearms is a health issue, for instance, could backfire. There are plenty of members of congress that don't fully understand the suppressor argument and they may decide that in the interest of better hearing health for all Americans, all firearms will be required to have suppressors.
Highly unlikely, I know, but nothing congress does anymore surprises me.
