My list wasn't meant to exhaustive. Honestly not much of a list, just a few examples. SpaceX and Nvidia are both examples of deep technical moats, as are some of the others mentioned by commenters.

I agree with you that many moats are regulatory, but disagree that most moats are. Networks are powerful moats, customer lockin can work well, brand is a strong moat (at least for a time), speed and culture can function as moats.

Fwiw, I don't think any moat is ultimately perfect. Moats themselves are not meant to permanently stop an attacker - they are delaying tactics at best. Companies that stay ahead continuously re-invent and rebuild their differentiation and defenses.

Relationships with suppliers and customers are what gives any business most of its value.

I don't consider that to be part of a moat because you don't have to cross it before you begin competing with the business. Establishing suppliers and customers is just competing with whatever businesses would also want those deals.

A technical moat is knowledge that you have to have (maybe across multiple employees) before you can even begin to start competing. It's rare to come across any technology that couldn't be cloned by a few smart engineers in 6 months. Much more likely that you aren't allowed to build or sell the technology, or you don't have enough capital, or no one will sell you the parts, or it's illegal to start the business in the first place.

Network effects didn’t save MySpace, instead companies need to constantly adapt or risk disruption.

Historically many companies seemed like they had a much deeper moat when the real risk comes out of left field. Blockbuster didn’t die because a competitor suddenly opened a lot of stores instead the basic economics underpinning their business model changed.

Nvidia faces similar risks because they depend on access to world class fabs at reasonable prices. If hypothetically Intel suddenly develops a much better node and then keeps executing Nvidia could be left in the dust with little recourse.
