Make it 250 kbps and without limit, or limited to at least 100 GB. Speed can be waited out. Bandwidth limits, not so easy. Or, if 5GB then for a day.
What’s “true high speed”? Where’s the cutoff?
The most obvious way to achieve anything close to this goal is to force telcos to not stay in the way, and allow formation of tiny local co-ops, microISPs for small regions. The same model that the power distribution network used in 30’s. The cost of the necessary point-to-point microwave links is pretty low these days.
