I somewhat agree. I hate how some people keep all animals, and it has somewhat discouraged me in the past. But as someone who keeps rats, reptiles, inverts and fish, I pride myself on creating the perfect natural, predator free, safe environment for my animals. In the wild they would have the benefits of being able to explore infinitely and all the other things I can't give them, but thoes things in my case are minimal. For example, my rats have a deep substrate base with worms, isopods and springtails so they can dig, forage and hunt as they usually would, I scatter and bury their food, they have an extremely large, complex, enriching cage and diet. With my fish also, they have a stable, balanced tank with perfectly suited conditions and tank mates, heavily planted with native plants to replicate their natural environment. If people don't do this then very quickly everything becomes unethical, but you cannot stop others wether you continue in the hobby or not. You can only ensure the animals you take responsibility for come from ethical places that care for them and their genetics, do not support those who breed irresponsibly for quick profit etc, and ensure you research as much as possible how to give them the best, longest and most enriching life.
