A beautiful idea and a beautiful project, but tell me, if the developer benefits, then what benefit will I get? It's like a game, nice, but it does not bring any money.
Like any other token, the
standard ERC-721, its value and actual cost depends on the
rarity,
uniqueness and
attractiveness of the characteristics.
Improving your own section and getting different characteristics for it, you have a chance to make it significantly valuable and sell it on the internal Marketplace platform.
Also it is worth noting that the profit from the project you can get is taking a perspective section of the sky and
renting it for ETH.
