The losses increase with distance, and decrease with higher voltages, which is why most cross country transmission happens at 740kVAC. But still, the energy you're using in your day to day life is almost always produced with 50-100miles of where it's consumed, because transporting it longer distances make losses uneconomical.

At long distance, the transmission losses are so uneconomical – that they never got built in the firt place. This is why you shouldn't look at current loss numbers, which already weeded out what was not feasible before.

Now, if transmission losses are near-zero, then yeah – you'd still get the same power for the same price & losses (for other reasons), but from 500-1000 miles away instead of 50-100 miles. Residential customers won't notice anything immediately because they'll pay the same due to initial capital costs and stuff. But decades down the line it would slowly, invisibly transform everything around you.
