My point is that "local-ness" and "dependence" are not absolutes. Endeavours of different kinds may be more or less local, more or less autonomous.

If my municipality's electricity authority buys a turbine, it isn't buying local production and it isn't independent of non-local heavy industry. But that turbine installed on the river is local in the sense that the energy source is local, the finance is local, distribution is locally-owned, and the management is to some extent local. There's a degree of dependence and a degree of autonomy.

If I have a farm, that has distinct characteristics of "local-ness": the soil, the climate, the hydrography limit or potentiate my production. That production may also be locally sold. I cannot produce without the aid of industrial goods (tools), but the tools are useless without the other factors of production that I possess.

Why this matters to me is because, in my view, the richness and liveliness of a democracy are enabled by a degree of local autonomy, and depleted by the alienation of authoritarian top-down structures.
