While you may burn power in Gaia Project, unlike in TM, you need them for satellites for federation/alliance formation.
Unless you have a source for power token income, you have to think judiciously if you are willing to burn them up.
True, and you don't have as many tokens to begin with. However, there is a power action you can take to gain more power tokens, and there is a free action you can take to buy more power tokens by spending ore. So there are several ways to get power tokens, even if your PI income does not give you one.
