Why does Arizona hold elections the way they do?

This is a question I haven’t seen asked or answered…does Arizona get higher turnout or participation from their system that seems to be extra slow and tedious to calculate? Is it cheaper? Is it faster for citizens to vote?

All I ever read is the “why” Arizona takes so long (mail in ballots dropped off until Election Day, curing signatures, yada yada)….but I don’t really know why any of us should care about the why. Im more curious why do they run it this way? What’s the benefit and is there data to back it up? Because the “cost” of the time consuming process that takes weeks seems steep to make it “worth it”

And if the benefit of their system is “worth it”, it has clearly known limitations that could be solved by

1) moving the deadline for ballot drop off a week earlier
2) hiring 10x as many ballot curers or however many is needed compared to how many they have that takes weeks

They have 49 other states to model after…they have their own data on how their process takes too long…it’s so easily solvable. So again, why? What’s the benefit of mail in ballots up until poll closed with signatures instead of ID?
