But if we raise the price of helium to prevent depletion of resources, helium will be expensive too.

Although artificially raising the price of diamonds seems to have been an effective strategy for the diamond industry, that is in part because they found a marketing angle where the high price of a diamond engagement ring is a strong emotional signal between a prospective couple. In most markets, people simply are not going to pay more for something than it benefits them. Raising the price can have the consequence of pushing people to go look for other alternatives.

Price has to be reflective to some degree of underlying value or benefit. Further, if creating helium comes at the cost of destroying more real value than it creates, this is simply a lose-lose prospect across the board, regardless of the price tag you can attach to helium.
