So you're saying that the pylons promote one way of building over another. That't true. Just like Zenith promotes the melee class over any other. See this comparison makes sense because there are many other things like this in the game. You could argue that the corruption is worse than crimson, but they have their ups and downs. Terraria has many things like this and if they made everything "balanced" and "satisfy every player" the game would be bland and the same every playthrough. Imagine if the corruption and crimson where just aesthetic differences. Or imagine if every classes armour and damage where equal. The pylons system does promote spreading out your NPCs, but it doesn't stop people from building whatever they want. You can copy and paste your main village into a 1.4 village and make some boxes in different biomes, or big villages too. Building a big central village isn't a way to build, it's a way to play the game. And there is no problem with that. (Of course excluding the pesky shopping penalty with keeping your NPCs unhappy)You'll need to scatter your NPCs out for that, though. Just don't see why this is locked behind one way of building.. nothing else in the game you can earn/unlock is based on build preference other than NPCs selling certain items in certain biomes, and that's already kind of not fun having to do, since it's more of a hassle, and with pylon lock, a build restriction. Having them craftable and more accessible would include everyone- those who like to spread NPCs out and those who do not.
