But I gave an example, large pools artificially increase block fees.
If the 3 or 4 largest pools on the market align, they can create Ordinals transactions with high fees, knowing that they will get the money from these fees back in the blocks they mine.
Mining pools can attempt to "spam" the blockchain, a topic which we have discussed in the 2023 diff thread in the mining section, but they don't need Ordinals for that, in fact, it is easier for them to create non-Ordinals transactions that are larger in size.
But in regards to fees, Ordinals are just a currently living proof that the main chain is incapable of processing many transaction at low fees, the type of transactions is irrelevant to the fee, you may argue that the type of data they leave on the blockchain is useless and should not be on the blockchain, but fees would still be this high and worse if 1% of the population started using BTC on chain for daily payments.
