I tend to agree with this.
People are finicky and get bored of things quickly once the novelty wears off.
In Canada I had the pleasure of keeping a bearded dragon, green iguana, crested gecko, house geckos, skinks, red-eyed tree frogs, and aquatic african dwarf frogs.
I also had access to and took care of chamelions, tokay geckos, boa constrictors, box turtles, leopard geckos, poison dart frogs, different tree frogs, other snakes, etc.
But now I live in NZ and am limited in my selection. But I've also realized that out of all herps and fish i've kept before, I still felt equally about them all. Meaning that it didn't really matter if i was keeping something really cool and rare or something common because in the end, caring for each animal was equally rewarding and fun.
Maybe I got it out of my system while growing up that makes me feel this way. But I think that people here in NZ sometimes put too much value on something just because they can't have it. Like jc and insect direct mention, NZ natives are priceless and it is important to protect them as a primary focus.
If you wanna feel like you've got something exciting and rare, why not apply to keep NZ natives. Then you can go on all the overseas reptile forums and make them drool over the animals they can't have.
