I find the entire scaling debate to be non relevant and, at this point, misdirection. It is also why I literally laugh at the BCH propaganda.

Wall Street does not care about block size or transmission speed. It cares about liquidity and ROI. The only one who really can offer that is BTC. For all their ills, there is one thing Wall Street can do and that is raise money.....lots of it. The technology side drove the show, we are about to see what happens when finance takes over.

As for your points specifically, you are right on. From a technical standpoint, I think LTC ends up right where Lee wanted it...as the faster more flexible chain to compliment BTC. In the end, as it stands now, neither can compete with the centralized system of Visa in terms of transactions per second. Even ETH, which gets a lot of attention is at 25 and might get up to 2500....Visa does what, hundreds of thousands. Now that isnt to say it wont be figured out...there area lot of smart people involved in this.

Slow money, fast money...great terminology. In the end, you are probably going to be correct. BTC will be used to buy boats, cars, and to have public documents (you will see smart contracts there at some point) such as tax records while LTC handles some of the smaller ones. The advantage to Atomic Swaps is that, ultimately, it will occur between any blockchain...so other coins could play into it.

I am bullish on both BTC and LTC...obviously bearish on BCH...and dont even think about BTG.
