The problem, Biv, is that none of those things have ever been equal. Since there are no NPC shops anywhere to buy items, anyone wanting to play singleplayer style, which the game heavily encourges right from the very beginning of the game by planting you in the middle of no where on a random planet, the only way to get stuff is by gathering, building, and crafting it yourself.
However, because Recipes are locked behind skill points, only gained by leveling, and you have a limited small number of skill points, and a whole lot of skills to each kinda job, it’s impossible to play single player, unless you go out of your way to make multiple alts to do each of the jobs, which is no fun at all.
Secondly, if playing it from an MMO style, then you have two options to interacting in the ‘MMO’ setting. First is gathering and creating stuff to sell to make money, so eventually you can ignore the gathering part and just buy the materials cheap and sell the item you craft at a profit.
The other option is to be the buyer, and buy the materials you don’t have to craft items, or even just buy the items if you can’t craft. But here’s the catch. Unlike resources, Money is very very limited. Unless you exploit the game, creating and deleting alts while giving their money to your main to generate infinite money over time, eventually you’ll hit a point where you just can’t afford anything. Especially none of the higher tier stuff.
So while you can interact with people at first, such as buying new tools to replace broken ones, or even better tools to use. Eventually you run out of money, with very little regained daily, at which point you’re forced to stop playing, unable to progress, cause you don’t have the skills to craft the stuff, and don’t have the money to buy the stuff.
Do you see the loop yet, Biv? Unless you’re a Gatherer, AND a Crafter, you fail at the game. You can’t just being a Gatherer, you can’t just be a Crafter, you can’t just be a shop owner, you can’t just be anything. You can’t play however you want. Gathering and Crafting combine is the only way to actually play the game.
And if you wish to prove me wrong, then I ask a simple question.
Can you name me a player, with no alts, and no getting free resources/money/tools from friends or guilds, that only does 1 job? That only Gatherers? That only Crafts? That only Builds? And that can do said job long term, from beginning at lvl 1, to end at lvl 50?
Because I’ll be willing the bet that the answer is no, that you can not think of a player that can do that.
Because the game isn’t balanced, it isn’t fair, it isn’t meant to be played any way that people want. The game is designed to be played a very specific way, and if you don’t play that way, you very quickly run into issues. And while money can support any play at first, that very quickly runs out in a few days.
