The Larkinson Clan designated medium-grade and high-grade superdimensional matter as strategic resources.
This meant that they had to be placed in secure vaults whenever possible. Not just anyone could take the materials out and use them however they wanted.
They needed to submit an application and wait for approval before withdrawing the permitted amounts of strategic resources.
That was not the end of the story. They had to make use of the materials in a timely manner and submit their logs and reports to prove they made meaningful use of what they had obtained.
If they did not do this, then they would get into serious trouble.
Just because the Larkinson Clan had grown wealthy and flush with phasewater and other resources did not mean that it tolerated waste!
If mech designers or other professionals could not be bothered to provide a proper accounting for their work, then they did not deserve to get close to the clan's strategic reserves.
