That approach does not scale, at all. If Lightning were ever to grow beyond a toy network, it would completely collapse.

(It's not commonly recognized and impossible to talk about without any pointers as to where the problem should lie)

In practice this needn't be an issue:

* Most nodes will rebalance, open and closed channels based on neighbour uptime and reliability

* In practice the LN network is expected to have a little but of a hub-and-spokes topology. So in practice you will almost always have a couple of well-known highly connected peers along your route

So it's a fundamental issue that will become a reality in worst-case scenarios but something that can be mitigated.

As one of the comments noted, we're somehow able to do this for TCP and TOR.

You linking to the /btc subreddit makes me think nothing anyone says or any developments will ever convince you (correct me if I'm wrong). In that case, I think your efforts are better spent in focusing on bringing value to the efforts you do believe in rather than telling others they're bound to fail.
