The Bitcoin entire blockchain is nearly 100GB today. That's totally unfeasible for anything less than a 10 Mbit/s + connection.
Less than 28 hours to move that entire database over that limited link. Cry me a river.
Uh, yeah. You're agreeing with me: that double-digit Mbit/s is a rough minimum, below which most people will be put off from trying. And that minimum increases 1MB every ten minutes.
Tell us again about how you want the minimum internet connection to d/l the blockchain to start increasing at 16x times that rate, lol

You have no point to be made. Shooting for "the minimum internet connection" is stupidity. The minimum internet connection of which I am aware was unable to download last year's blockchain. All things being equal, more nodes are good. However, stifling adoption of bitcoin is not worth catering to the lowest common bandwidth denominator - who won't run nodes anyway.
