Also, regarding taxes being more centralized than local. I'm not sure about your state, but every other municipality seems to have some major project going on, such as rebuilding a larger/newer school or something. When those projects are pushed, people are told "don't worry, our city only has to cover 6-8% of the total cost. The state is going to pick up the rest of the cost." And, people either don't realize that they're still paying for it, since the state's money comes from somewhere, else they realize that hey, everyone else is doing it, so they should get their share too. But, there have been a hell of a lot more projects approved than would ever have been approved if it were only up to the local communities to pay for it. "No way, I'm not paying for that project. Huh? Well, sure, if someone else is paying for it, let's build it."
Tell you what though, if my local services were provided by the state, rather than locally, my community would insist on all of those same services that the majority of other people in the state are receiving. Street cleaners go down your street? They never go down my road. I want them now, and you get to help pay for them. Garbage collection? Hell yeah! I hate driving to the landfill every couple of weeks to get rid of my non-burnable garbage (plastic). The 3 foot high, 200 foot long pile of leaves that I raked to the edge of the road over the course of several days before spending another 4 hours & breaking a rake just loading them into a trailer (many loads) and dumping them on our side road - Hey, you guys need to pay a little more in income tax or sales tax, because I want the town to pick those leaves up for me from the edge of the road.
In short, you are going to help subsidize every community that suddenly decides that they want their cake too. Those communities have worked hard to keep their own property taxes down, but now that we're all paying the same sales tax, or income taxes, why the hell shouldn't we get identical services.
Hopefully, this helps you realize that local spending would end up spiraling out of control.
