You didn't show that the law causes any problem in any way.
If the woman or her family wanted her to have power they could either have her in her own country or they could go through the proper channels to bring her in legally. The total weight of all consequences for coming here falls on the woman.
It isn't the utilities' job to worry about the consequences a foreigner may bring on themselves by illegal entry.
The problem is that the 95 year old citizen gets cut off and dies as a result of the utility not doing due diligence.
“If the woman or her family wanted her to have power they could either have her in her own country.”
You’re missing the point. I’m talking about a citizen who gets cut off for failing to provide the documentation, either through not seeing the notice, or understanding the notice. This already happens every year during cold snaps and heat waves, the utility company cuts an elderly person off without investigating as to the actual cause for non-payment.
It’s happened before and unless they are very careful, this will happen again. The result of which will be a lawsuit.
