I mean I really don't think this is going to change anything, the government is just trying to increase revenue any way that they can. So it's not like they're openly promoting for Bitcoin, I think they just come to terms (with research and stuff) that they'd be able to do well with accepting bitcoin, maybe save some money on fees and then maybe even bring in some more tax revenue. So this isn't be done out of good faith, it's just being done in general.

If people can pay tax in cryptocurrency, that makes it a currency not an asset (for example no-one pays tax in gold or diamonds or real estate).
Arizona is trying to attract cryptocurrency enthusiasts to their state, and more power to their elbow.
