So eventually we might be able to trade money with other players, or at the very least ore which can be converted to money. This makes for a full-blown economy, but with nothing to syphon the money away aside from merchants and dying, more pixel sinks will be needed to avoid massive inflation. I had a few ideas of some pixel sinks that are useful enough that people would use them. If you have your own ideas, please share them here as well! So I have two main ideas. Changing the spawn point on your planet could have a small/medium fee attached to it, allowing you to 1) be able to save where you are on a planet if you have to quit, and 2) find a better location than spawn for your home base. An upgrade to the ship's teleporter that allows you to beam back to the ship from underground. Not only could the base upgrade cost a decent sized fee, but there could be a cost to using it: 10-20% of pixels on hand. It's cheaper than dying to transport back, but it's useful enough that there's a cost-benefit analysis to using it. Are you willing to sacrifice 20% of your pixels instead of walking back? Edit: I also suggested an alternative to voxel banking here that can also work as a pixel sink.
If the 3d printer could print everything (for a hefty price) that would be a good pixelsink. It would also be nice being able to drop a bunch of pixels into the 3d printer instead of having to fly across the galaxy because you realize you're short 3 green dirts of what you want to make. Ship upgrades would make good pixel sinks. There's your suggested bank upgrades in the other thread. http://community.playstarbound.com/...ike-progression-rather-than-punishment.43775/ A random chance thing like terraria's reforge system is always fun. Maybe just like the reforge system, or maybe like lineage 2's enchant system where you pay pixels to increase the weapons damage a small bit, and can keep doing that, but every time you do it it has a chance to reset the enchantments to +0 or even break the whole item.
Interjection: Here is a marginally relevant chart, provided free of charge. Addendum: Some hashed out ideas... Not sure I'm too fond of voxels yet. Feels like reinventing the wheel. With bread-sticks.
