Memecoins are shitcoins and a scam. They have some small value becuase some scammed people paid for them. 99.9% regret it after they get rekt and/or rug pulled.
Bitcoin is different and that is why it is valued at $2.2T currently. Again its not hard to come to consideration that spam has 0 value. Also no one was arguing against to possibility to put hashes up to 40 or 80 Bytes in OP_RETURN. 100 000 Bytes of spam is an attack on Bitcoin.

Fees plus spam filters are better than just fees.
Bitcoin is thermodynamically sound money, not thermodynamically fucked up spam and csam.
