Using of a blockchain for gaming would be a stupid way to use it, just like dick pics and fart sounds in the Bitcoin blockchain. Nothing of those truly need censorship-resistance. But, from the technical viewpoint, Ordinals are valid transactions that follows the consensus rules. Some people could argue that it's an exploit, its supporters argue that it's a feature. Both can be right depending on the person's point of view, but from Bitcoin's point of view, they are valid.
Ordinals NFTs are just "inscriptions" on the Bitcoin blockchain. They don't contain data from the NFT itself. As long as network fees are paid, the transaction is considered valid by the Blockchain. We could say "spam attacks" are also valid transactions, even though their intentions are malicious. Eventually, fees will rise to a point where it becomes economically unfeasible for the attacker to continue spamming the network with transactions.
I believe the same will happen with Ordinals in the long run. The higher the rate of NFTs inscriptions, the higher the fees will be. Once that happens, there will be a decline in NFT inscriptions, paving the way for normal users to perform transactions at a lower cost. BTC is strong and resilient, so there should be nothing to worry about. Just my thoughts
