The main issue with the hardforks is that they are motivated by greed. By hardforking they generate a new currency which gets traded and even if it's valued at 10% BTC (I'm looking at you BCH) people will make money from it. I agree with you that every hardfork dents people's trust in Bitcoin and in the crypto environment. One of the main characteristics that make Bitcoin valuable is that it has a limited supply. Hardforking into a new currency is shortsightedness and greed, the one thing that can bring this whole thing down is if people lose trust in the blockchain. Let's hope that the devs and miners can come to terms and find a solution that is beneficial to the cryptospace in the long run.
