Is Our Ecclesiology Fundamentally Flawed?

I'm nearly done with my seminary degree (course work is complete and I'm in the final stages of my thesis editing) and so I'm going to finally be getting the reading time I've wanted.

In addition to that I've been pondering something and I'm curious if anyone has feedback. Related to our ecclesiology. Where did we get the notion that our ecclesiology should be about how we govern our local church building's institution rather than the church body in a location?

For example, most modern ecclesiology seems to focus on what it means for an elder to be appointed in the local church (differentiated by a building or a denomination). But what if our ecclesiology was about how we as a church body in a location (city or whatever) should interact with one another?

I ask this because in my brief study of the word "church" every instance I've found refers either to the Church Universal (catholic church), or to the local body (as in the whole body of believers at Corinth, not "the meeting Bob leads at 143 Roman Road").

If you have any thoughts on this please send me an email (rogermugs at gmail dot com). I'm curious to process this a bit before I write and publish something more completely.
