No doubt that his paths to finals have been easier because he plays in the East. And I'm not trying to compare him to Jordan, although I think maxent's point is important: Jordan's Bulls teams were comparatively stacked - he was always playing alongside one and sometimes more than one future hall of famer for the championship runs.* LeBron was playing with some bullshit after Kyrie went down. There was basically no one else on the team who could score reliably.
I grant that he pooped the bed in 2011, that Jordan was better in the playoffs, etc. But that's all beside the point: The point is that LeBron was BY FAR the most valuable player in this series. Sure Iggy fucked his shit up on D, sure he shot badly from 3 and from the line, sure the advanced stats are not great, but the fact is that no other player had even close to as strong an impact on his team's performance as did LeBron. Again, if you want the MVP to mean "best player on the winning team," then okay. Iggy getting it shows that at least a fair number of media people think that. And Iggy was awesome! He was the MVP for the Warriors without a doubt! But I prefer a literal reading of the term and by that reading I just don't see how it could be anyone but LeBron.
