I wonder, could the following be true: any startup that faces the problem of unscalable implementation will by then have the necessary resources to resolve the scaling problem? Because, by the time you run into scalability problems, you'll probably have enough investor|customer money to invest in re-architecturing your code?

That implies that startups charge money for their product/service. More often than not, sites that need to scale for millions of users are "free to use".

He also mentioned investor money. Investors tend to invest in sites that have tons of users even if the site is unprofitable at the time of investment (see youtube, digg, facebook).
