Sorry, I've gotta disagree with you on pretty much all points here.
It's a two way street and I don't think you grasp the revenue that the Counties and the State of FL receive from WDW and it's related tourism and employment. It's the biggest single site employer in the Untied States and the taxable assessed value of the hotels and especially the DVC resorts is astronomical (think hundreds of millions to billions of dollars...each). It's not just a cash cow, it's a golden goose riding a cash cow down a street made of gold.
You may not know this, but somebody (Roy O probably) at Disney was smart enough back in the day to get the state to create a political jurisdiction (several I think) just for Disney. So they are pretty well insulated from the kind of nuisance complaints you describe (owning close to 40 square miles also helps) and unlike any other park in the US in that respect. I believe that the whole of the WDW resort is within the Reedy Creek Improvement District- that creates all kinds of low cost ways to operate and finance infrastructure, fire/rescue, police, utilities, roads, etc. Then they created the City of Bay Lake and the City of Lake Buena Vista. Each has only a hand full of residents- all of which Disney controls. I don't live in FL, so I don't know all the ins and outs of the political structure, but I do know a good bit about politics and jurisdictional structures in general. The only way anyone could vote people into office that could force Disney to do ANYTHING would be in County (WDW is located in 2 different counties and I'm not even sure what regulatory powers FL Counties have over cities) or state elections. And Disney is one of the largest political contributors in the State of FL. So while I guess it's possible theoretically, to say the kinds of things you describe are unlikely would be a huge understatement. Also keep in mind that in many instances it's unlikely that they could pass laws that only impacted WDW- at least that would stand up in court- as the bills would likely have to be structured in a non company specific way that would also hit Universal and probably Sea World. State level bills would probably also hit Lego Land, Bush Gardens and probably other smaller attractions.
But back to the main point related to AP's... They don't need to be A-holes about it. If the amount of local AP holders becomes a real problem, they will just do what they are doing at DL. Traditional AP's will be "reimagined" into a new program that in some way limits locals from attending at peek times and too often...and I'm sure price increases are part of the plan regardless
