This is missing the key point of the article which is that there are also taxes to pay, not just the strike price. What you're saying is valid -- even the strike price can be a lot for someone to afford on their way out without any liquidity. But it is very important to understand that it's much worse than that at "successful" startups that have increased in value substantially over those 2 years. You also have to pay AMT (28%) on much of that gain in value, which could end up costing even more than the strike price itself.
