The power supply beam is useless to most players, especially after players have a base started. Most servers will either give you at least one power block when you start, and/or give you enough credits to buy one. Only hardcore servers where players lose their items and credits (and have to start from scratch) would need it when setting up their first factory on a planet, but they wouldn't have it because they lost their items.
Instead of needing a power supply beam, why not just have each factory provide enough power for one block to be made when it is added to a structure or planet? This way one power block could be made without needing the tool. The suit used to make the factory has unlimited power, so why doesn't it "charge" the factory enough to make its own power source?
