Imagine how hard it would be to buy stuff or use free services if you actually had to read and understand the contracts every time.
Ok, I’ll just quickly check on Google maps what’s south of Mongolia. Oh, I need to read all that before seeing the map? Well, maybe later. Don’t really have the time for that right now.
If that’s what life was like, laziness would win nearly every time and companies would have hardly any users or customers. Eventually some companies would probably make super short contracts in order to lower the threshold.
