Not such a great decision for consumers
This decision is about providing undeserved income to states so that fiscally irresponsible politicians can squander the money. It's similar to legalizing the sale of marijuana which is only happening because states can tax it and generate more revenue. In every single state that has legalized the sale of marijuana the cost of social services and crime has increased dramatically according to independent auditing and even disclosures by Colorado and some other states. In the end the populace pays more and gets less while creating headaches for e-tailers.
