Why build anything on ethereum network???

With gas fees so high I legitimately do not understand the incentive at all to put an NFT or anything on the ETH network. Why do people do it?

Please don’t rail me, I’m just a genuinely curious person with an outside perspective and no idea why the hell someone would use a network that costs $150 to move a $50 NFT?????? What am I missing???? Other networks do the same for a small fraction of the cost I am so confused.
