I can only speak for myself, but if prices doubled overnight, owning a domain would not be feasible for me because I don't conduct business or earn income on the domain I own, and the only reason I went for this fairly obscure TLD is because it was the cheapest decent one I could afford. Some of us aren't "businesses", and unless you think we don't deserve a corner of the internet, you'll find there's tons of us.
Sorry but yes, if you’re not making enough money from your .com to pay (say) $50/year, I think it’s perfectly fine that you can’t use it for your random hobby project. The lost value that comes from .com being messed up is so much greater.
.com is very clearly commercial so what I had to say isn't applicable to it (which is why I mentioned I use a relatively obscure TLD like .site or .xyz).
