&gt; <i>Good thing I don&#x27;t need to these days; I fear for those who do</i><p>Oh but you do, you trust countless of people doing their jobs right so that you can have electricity, clean water, safe food and peaceful streets. <i>Civilization</i> exists because of trust.<p>And one has to realize that trustless systems come with a cost - they have <i>stupendous</i> overhead. Consider all the layers of bureaucracy companies (or the law) employ to protect themselves from malicious actors. Or, consider Bitcoin. It&#x27;s good to have, and maintain, trust-based systems because they can get the job done much, much more efficiently.
