Call me cynical, but I would rather rely on written regulations and systems of checks than human altruism.

True. Those who only care about meeting regulatory requirements are not going to care if the regulatory requirements cease to exist. Those who care about security may be dismissive of regulatory requirements, but they will do so primarily when they are insufficient or when they conflict with their opinion. In the former case, they probably have the ability to go beyond the regulatory requirements. In the latter case: while I won't claim that regulations are perfect, I would trust them over the an anonymous person who may be going on anything from their personal opinion to legitimate research.

Currently, besides if you use cryptocurrencies, I don't think you can rely solely on "written regulations and systems of checks", somewhere along those processes there are a bunch of humans with their altruism (or lack of), taste and daily life moving those processes along. And judging by the state of the cryptocurrency ecosystem, this is probably a good thing more than a bad thing.
