Missouri STR proposition help

Hi all. I recently got an email from HomeAway saying my state is working on legislation to open up STRs and limit local governments prohibiting them. And then the listing sites will collect taxes and submit them on our behalf. The full language is here: http://www.house.mo.gov/billtracking/bills171/hlrbillspdf/1263H.06P.pdf

Is anyone familiar with legalese or have similar measures in their states? I don’t want to call my representatives until I know this is actually to my benefit, but it looks good to me. Thanks!
