This strikes me as another variant of the "just 1%" fallacy of the bad old dot-com bubble days. Back then it was common for a startup to enter an industry and use an overly simplistic model to justify the viability of their business. Often it went along the lines of: this market has X (big number) in total annual revenue, if we can capture just 1% (or some even smaller fraction) of that market that's Y dollars (another big number).

Of course, these are just silly math games to hide the true difficulty of their broken business models. It doesn't matter whether you're talking about 1%, 0.0001% or any fraction, that doesn't make acquiring that business easier. The difficulties of growing a business into multi-million dollar revenue territory are still there even if the total market is huge.

There's no shortcut, and even as the market gets bigger there still won't be a shorcut. There are always trillions of dollars on the table waiting for businesses to pick them up, but it typically takes a lot of hard work to build something with any degree of value.
