Who benefits from government services and who makes decisions about how those services are supported are two very different topics. In the examples you listed, there isn't one huge federal mandate setting the exact level of road, sewer, storm water, ambulance, or fire services. There isn't even one by state. The level of services, how they're provided, how they're funded are all driven by the local government accountable to those who fund them through taxes. Except for this now.
It's not like I can show up in your town and demand that your town provides the same level of ambulance service as is provided in Disney World. That decision was left to your local government accountable to the people who vote for and fund them. Except for not in Disney World anymore, where the level of ambulance service is determined not by those who are governed and taxed, but by an unaccountable appointed administrator.
Who can receive the service is the same for both.
This is confusing providing and ability to use a service with how it is managed again. It's mixing two different topics.
Everyone who is within the jurisdiction and governed by and funds the district should get a say in the level of services provided by the district. Anyone not in that group is free to have an opinion, and that opinion can be ignored too. In the past, everyone subject to this governance within the district had a voice proportional to the district structure, now they no longer do. That the largest voice was Disney is irrelevant. Much like I can come to your town meetings and demand better ambulance service, and your government can ignore me.
