There's deep stuff here, and you're right, much of it can be reached by shore, or a quick boat ride. In Carmel especially, sites in the 200'-300' range can be reached from shore. And people make those dives regularly, there's an active tech community here. One day in the parking lot at Pt Lobos, a group of folks on rebreathers showed me GoPro footage of a 15' great white shark that had buzzed right by their group at 175' that day, and those guys were ecstatic. I have dived the shallower parts of these sites, to 100'-120' or so, and seen a lot of cool stuff.
Don't get me wrong, I'd like to do those deep local dives some day if I can. If I ever do pursue tech training, I think it would be for penetration dives, or maybe for deep sites that are truly worth it (Truk comes to mind, so do the wrecks in the Great Lakes). And at that point, much of the cost would be sunk, and I'd be open to local tech dives. But, for me, plenty of the great local stuff is in the shallower depths anyway, so coughing up 4 figures for training, and then either 5 figures for a CCR or 3 figures per dive on Tx, just doesn't pencil out.
To the OP: put another way, everybody who buys a double setup also ends up with a singles setup. But, the vast majority of divers are happy with a singles setup, and never end up needing doubles, so that is the sensible place to start.
