I think problem is that your argument seems to come from a prior point of view, and doesn't assume good faith on the behalf of people working on smart contract problems (declaring them in whole fundamentally unethical). I would suggest that a better way to pose your point of view would be to ask, "Are there ways to mitigate the automatic triggering of actions in smart contracts?" Posing your point of view as a question like this would be more likely to foster a healthy discussion because there are certainly ways to mitigate the extent of automatic actions (multisigs etc...). And who knows, everyone might learn something as a result of the discussion!

Disclosure: I work in the cryptocurrency space and generally think hackernews doesn't know how to have productive discussions about cryptocurrency.
