A nice enough attempt at quantification (for an undergraduate), but there are three flaws that graduates should fix:
1) The work posted is partial/marginal analysis -- simple enough and good enough for indicators. Better would be a global/matrixed approach, perhaps a multi variate equation with multiple objectives & constraints.
2) The work posted is not risk adjusted -- the threat of barbs and AI activity merits some 'risk adjustments' either in funds set aside to buy back/replace losses or in defensive units to protect assets, deter incursions.
3) The work posted is static analysis -- adjustments exist due to the dynamic aspects of the game. Given the opportunities, the rate of return on investments is not constant nor is the opportunity cost of partaking those investments. Better analysis would include the 'awareness' of the time horizon, the interest rate, and the val;uation of the overall objective.
