Businesses requiring heavy upfront investment and offering slow returns, like automotive chips, create formidable entry barriers. This 'terrible' model deters newcomers, ensuring a less crowded market and long-term defensibility for those who can endure the initial five-to-eight-year cycle.

Many investments labeled "value traps" aren't bad picks but are simply taking longer than expected to mature. During this latency, the business's fundamentals and earnings potential can actually improve, making it a better investment.

Despite its near-monopoly on leading-edge chips, TSMC maintains its dominance partly by not charging exorbitant prices.

New chip fab ventures face immense hurdles because fabrication is less like following a manual and more like mastering a recipe through decades of trial and error. This accumulated, non-transferable knowledge, likened to "cooking," creates a significant moat for incumbents like TSMC.

While low Capex is generally desirable, strategically investing in capital-intensive assets like technology or equipment creates significant barriers to entry. This reduces competition by making it too expensive for rivals to enter the market, thereby protecting your pricing power and market share.

VCs advised against the academic market, which took Qualtrics seven years to conquer. However, its high barrier to entry created an incredibly sticky customer base that competitors couldn't disrupt. This contrasts with 'easy' markets where customers churn quickly to the next new thing.

For 5,000 years, a mass-market pomegranate juice industry didn't exist due to high barriers.
