Exceptional strategic take. What you are describing is the core economic principle of "Barriers to Entry" or what Warren Buffett calls an economic moat.

The retail mindset always chases friction-free setups—businesses that can be deployed via software or simple replicable models in a few days. But the foundational rule of market dynamics is absolute: if entry friction is zero, profit margins will eventually gravitate toward zero due to hyper-competition and saturation. Embracing a "hard" industry with high capital expenditure, structural complexity, and human infrastructure is a massive filter. The complexity itself is your shield against market noise. It shifts your execution from fighting external price wars to optimizing internal capacity. True longevity isn't about being eye-catching; it's about building a defensive architecture that cannot be copied with a few clicks. Brilliant business perspective.
