Well, we already have tech that can provide us with virtually lowest latency physically possible without having to dig any tunnels - high frequency radio waves :) Of course bandwidth could be a problem but for pings it should be enough.

The point isn't to optimize for pings. It's to optimize for real use cases - video chat, web browsing, music and video streaming, etc. Most of these applications need at least a moderate amount of bandwidth.
