Ravencoin can handle Ethereums hashrate

I don't understand when people say alt coins can't handle all the hashrate.

Let's look at ravencoin for example.
Ethereum has a hash rate of 700, raven is 7. So at first glace, I can see how people might think mining profit will go to zero. But lets break it down.
Ravencoin uses kawpow, which is effectively half the hash rate as ethereum so take 700/2 and we get 350. Now kawpow is also asic resistant, which is most likely a significant chunk of ethereums hashrate. Let's say 30% to be fair. 350×0.70 gives us 245.
So, 245 is the maximum total hashrate that can go to ravencoin. However its stupid to think this will all go to one coin; it will be split amongst many, ETH classic, ergo, conflux and many more. So lets say ravencoin gets a fat 20% of that hashrate, which is 48. Ravencoin will now have a network hashrate of 55. Ravencoin has handled a hash rate of around 30 in the past, just to point that out. Anyways, This means ravencoin – in order to maintain current profitability – would only have to roughly x3 or x4 in price. This is not unrealistic, and in-fact I would go so far as to say ravencoin will already x4 in price before PoS even happens.
