Two things have to be taken into account here. Firstly the original post is from the point of a VC, and from the point of view of a VC, not hiring a sales team to actively pursue high value enterprise sales and partnerships in a market amenable to them represents the great evil of limiting traction and leaving money on the table. From the point of view of a micropreneur or small business not trying to win the entire market or go bust trying, it might be taking a massive business risk on something with far less predictable return than ramping up existing marketing spend.

The second is that there are millions of small businesses which aren't searching Google for software solutions to certain problems and yet are willing to part with cash if somebody shoves the solution in their face.
