Forgive me if it has been said already, but it seems to me that the compelling reasons for LL to integrate continents comes from their original charter of creating a world (and not a scattershot gaming experience) as well as what they care about most - money. While their cash cow is still kicking they should make efforts to retain customers and increase their value proposition. We have all seen how rivers, connected waterways, and roads push sales (real estate and goods), and the places where it has not (think of those large swatches of land that stayed empty for years). Connecting waterways and transit areas enhances our experience, so we stay, play, and pay. For each happy resident we pay direct dues, fees on sales, and add our IP that LL seems willing to capitalize on as well. I personally think that residents should not need to pay for a bit of server cost between our rented areas - it's already factored into their cost and benefit. Build a good product and people buy (or stay/join in this case).
