In other words BCS is a crutch that we shouldn't rely on 100% otherwise when it does run out we'll be left without having mastered our other dream manipulation abilities suddenly having to rely on them.

Ideally we'd be in the opposite situation, so proficient in our dream manipulation that we start forgetting that we even have BCS due to lacking the need to use it.

Recycling old equipment we no longer use/need would be a good idea.

A wise investment would be some form of crafting station. Like a place for smelting glass (we've got lots of sand on LoHaM) or ores if we can get access to those. That way we can still make stuff without having to expend BCS and we could use crafting to expand the arsenal further.
