It's a wasted effort on their part.
Much like the 'social media ban for kids!' Is doing in australia right now.
You can make a 3D printer using COTS parts, which means you cant really stop random people from making their own printers that conspicuously lack the 'mandated!' features.
Even things like resin printers just need a UV laser pot, a focusing collimator to sharpen the beam to an active point, a scanning mirror driven by 2 servo motors, and a build tank with a lowering floor, driven by a third.
Still essentially an 'on/off' signal, and six PWM capable gpios. Throw in some dumb endstop signals, and you have enough to work with.
You could make it a bit fancier with a linear bearing sled to hold the collimator, then have a 4th servo actuating it forward and backward, so that the laser's focal point can better reach extreme edges of a larger build plate after being reflected by the scanning mirror.
I should point out firmware to get generic microcontrollers to do this job exist, and are FOSS, like Marlin.

Trying to 'kill' them with this legislation will be about as effective as the afore mentioned child social media ban. (Which has been anything but.)

Trying to ban it would be like trying to play whack a mole, with endlessly replicating moles.
