I think you are under the impression that the equipment being used is large and expensive technology.

I am under the impression that it is a relatively simple process which most anyone could do without a huge investment.

Therefore the concept of shutting these people down for trademark violations before they get to defrauding the casinos makes little practical sense. Those who would defraud the casino obviously are aware their conduct is illegal so a court order directing them not to do it is redundant and would likewise be ignored.
