Actually, that assumes a lot about the nature of the experiment and the Rocket's goal in making this mod in the first place. While we've all seen that it's incredibly popular as is, we've no idea the full extent of the things he intends to be part of it. The only thing we can state for certain is that the current set of features are incredibly popular. Subscription is the only method that makes any sense without killing what makes the game so unique. The only micro-transactions that make sense would be tweaks to the starting kits. Any purchases that added to that kit would ruin the whole point of the game. Even if the purchase only changed the starting kit for a single respawn, it wouldn't work. That model would lead to bandit/griefer gangs farming respawn points for easy loot. As for the whole issue of private vs public HIVE servers, it's a matter of game dynamics. Just like the issue of micro-transactions, a private server or HIVE alters the community dynamic. Once you set up restrictions on who can get onto a server, the cuthroat nature of the game drops. How a player is granted access to the server becomes a critical factor in determining social interaction in the game. Is it white-listing, friends only, black-listing, or some other structure? If it's a friends only server, the population is going to have a harder time reaching capacity than a black-listing server. White-listing servers will have the problem of managing access requests. On top of that, having private servers will add custom server rules to the mix. PvE only is just the tip of the iceberg. While allowing private servers might eliminate the issue with hackers now, it would also kill the most significant part of the game. Once the community is split, they aren't going to want to be shoved back together once DayZ goes standalone.
