How can you quantify how much someone else's time is worth? It totally interrupts your workflow when your power cord comes out when it's not supposed to.

If this happens several times a day it becomes old fast. Free time doesn't factor in. I'd rather take the 1/10,000 chance I (or someone else) trip over my power cord on any given day than have this major annoyance.
Frankly, if you're careless to the point where MagSafe 2 actually becomes useful and balances out the annoyance factor, then you probably deserve to have your laptop broken anyway.

Besides, with solid state storage it's not like you're even likely to lose any data if your laptop falls. And it becomes even less likely that your laptop will be damaged in the first place if you have a case on it. It's even unlikely that it'll get damaged (beyond cosmetic dents on the aluminium) due to how robust they are nowadays
At least a case is optional - I can't even buy a third-party MagSafe adapter with a stronger magnet or a different shape because Apple has an exclusive patent on the connector.
If Apple were so concerned about falls on their devices, why did it make the iPhone's back out of glass? Hell, why's the power cord so special? I have an Ethernet cord running from my Thunderbolt to Gigabit Ethernet adapter to the wall at work right now - what if someone trips on
that? What's the point of having "robust strong beams" and "rigidity" in your industrial design when you still need a weak power connector to prevent the laptop from falling to the ground in
one specific scenario, all while your laptop could get damaged in a variety of other ways that MagSafe does nothing to protect against?
