They're related though. The whole thing is a huge social contract that we all agree too, mostly.
Something being against the law only matters if someone actually enforces that law. If nobody enforces it, only the social contract of everyone following it volunteerily is left to enforce it. Depending on the thing they'll turn out differently with no enforcement or even with who steps in to enforce it.
With no district and no municipality funding and servicing the area, and the county not wanting to provide services for free since they are not budgeted and set up to provide them. What's enforced will become murky.
If someone were to go on a violent rampage in Disney Springs, I'm sure the county police force would respond. Funding or not, they're not going to just ignore that.
If someone is driving recklessly or causes a minor accident with no injuries, the stakes are signifigantly lower. The county could easily ignore that.
The effect of a "no turn on red" sign is almost exclusively based on the social contract, with some amount of enforcement encouraging that. Remove that enforcment by not funding it, and the social contrct will decline quickly, as a right on red is legal in many many instances. Likewise, the infraction isn't going to rise to the level that unfunded unplanned police force is going to go out of their way to deal with it.
