Would if one industry gobbles up an important resource to the point that other consumers lose practical access to it, shouldn't there be limits?
If others are willing to pay more, that a signal that more value is created if the resource goes to them rather than to the more price sensitive customers.
No. The other industries can bid for access to the resource, and under most circumstances, whether they are willing to bid higher tracks importance. Sometimes there are cases where something has significant positive externalities and so people are not willing to bid high enough, and then we can talk about some kind of government intervention (typically a subsidy that attempts to track the value of the externalities) but I don't see that applying here.
