We gotta some using terms like "Invalid State Changes" when we talk about to normies about decentralization. They don't get it.

Decentralization protects you from bad people having the ability to:  

- Freeze 
- Inflate 
- Steal 
- Censor  

the things you own.  

The more decentralized a blockchain the more protection. The more protection, the more value you can store on the chain.  

Chains like Bitcoin & Ethereum can protect things from FISC even from nation states.

I agree, but the next thing ppl usually say is that funds get stolen and hacked all the time eg: ftx , bridge/defi hacks etc etc. it's difficult to explain all the nuances and security assumptions.
