Тут просто некорректно переведено. На самом деле, ничего не "тратится", например, цитата про "Влияние":
The number of countries that can be in your market at a time is based on the market leader's diplomatic Influence, which is one of the main capacity types. Capacities are different from power/mana in that it's not a pool of points you build up and spend. It's more like having enough electricity to run a lot of devices. Influence is also used for things like alliances, etc. You get Influence primarily from having rivalries, your Power Ranking (Great Powers get a ton), and a few other things that add percentage modifiers.(отсюда: https://www.reddit.com/r/victoria3/comments/nhzt1w/victoria_3_everything_we_know_so_far/)
Просто чем больше Влияние, то тем больше можно, например, иметь стран в своем "рынке", и т.д.
