I don't think a large portion of the trip price is for government fees and permits. I think some boats in the Galapagos are able to price high because the government limits the number of boats that operate there.
Galapagos is remote though. Their costs to operate are going to be higher than say the caribbean or southeast asia where crew, supplies, and fuel are easier and cheaper to source. I would put it as a combination of factors for the cost.
