You forgot the cost of training.I think the decline in diving is due to the cost of equipment and the focus of the industry on destination diving. When the average Joe/Joan walks into a dive shop and sees $1200 BCs, $2,000 regulators, and $300 fins s/he will have sticker shock. When they see trips to far-off locations in the thousands then they may reconsider and try another hobby. Very few people have that much disposable income to spend on recreational activities.
