Please cut the marketing talk. Seriously, inclusive pricing structure? Sounds scary, especially that people are already reacting positively to that.
The things you named are the assets ED has to provide free of charge, so that the whole DCS business model works in the long run. An environment or a structure with single big modules (with great value) to play around with. Otherwise, at some point there will be a total inflation of DLCs.
Plus all the other problems that come with asset packs, like multiplayer problems, server problems (what if one player sees the building/unit and the other does not), splitting the community,etc. We can see the problem already at a smaller scale with the WW2 asset pack, which scares off a lot of new players and is one of the core reasons DCS WW2 hasn't taken off yet (ha, pun!) and remains some kind of expensive tech demo.
If what you are proposing becomes the future of DCS, and it becomes a simulation where paid packs with buildings or non-driveable vehicles and other cosmetics (maybe even airport updates) are a reality, I would seriously stop investing more money in this simulation.
DCS now lives off its future potential and growth, and more barriers would kill at least the latter.
But not to be totally negative, why not go the full way and start making period-specific maps?
