They won’t, those plans are exclusive for business users.

They do. It is true that businesses are less likely to be emotionally driven, and more likely to have people on staff calculating exactly what a service is worth to their business. If you tried to charge them $80 they'd laugh and walk away.

There are better plans you can get as ‘retention plans’ per say

Yes, similarly the consumer who refuses to pay top dollar will see a lower rate come their way.

Granted, it is unlikely a consumer will put on as much pressure as a business. If the operator says: "Nope. It's $80 or nothing" the business will, again, laugh and go use two-way radio or something else instead. A regular consumer is more likely to find value in having such service – their friends don't have two way radios or some such – thus will be willing to pay more.

Also, no one is begging to pay $80.

They are. While the number was arbitrarily selected, it is pretty clear that lots of people are keen to pay an amount in that ballpark, if not more. The price is set by what the customer is willing to pay. Why would you charge them less?
