Hello Binance Family

I have 2 questions,

1) Is it true that the NFT without gas fees is worthless?
2) Opensea offers a free NFT listing on Polygon, the problem is that to unlock a sales transaction, the creator must first have 2.ETH, the equivalent of 3000 or 4000€, for an exchange, why such an embarrassment, so it comes back to the same. It's not free.😵‍💫😵‍💫😵‍💫
