Yes i agree that's why i 'm saying that there are no expensive or cheap coins. You don't have to buy 1BTC. You may buy 0.017 btc instead of 1 ltc since they are pegged.
Don't forget that there will be around 16 times more 0.017 fractions of Bitcoins than "full" pieces of Litecoins.
That's not an issue whatsoever. Check the bitcoin.org faq
