in my opinion jpegs are ddos attacks

The assumption that spammers are the ones that will get priced out by fees and not the people using bitcoin as money is a problem. We can’t assume that the fee mechanism will lead to the outcome we want (the network being used for monetary purposes) I hope we learn from SF making it easier for homeless people to shoot heroin on the streets because it’s “safer” this way and they were gonna do it anyway, so why bother implementing the law

No. That doesn't make the Satoshis in that transaction and more or less valuable as money. They are wasting money in my opinion. They are still making a financial transaction though.

Even if it is not jpegs it will be just shitty things. People still buy padlocks to hang on a bridge and symbolize their forever love. Yes they "buy" it whatever the price is. Even if the bridge exist to allow people to cross a river. So, yes, the price won't do anything to stop any shitty spam, and it will not always be jpeg, but also someone that want to put an entire book in it.

Spoken like someone that has no idea how much it would cost to put a book on Bitcoin

If padlocks were $1000 they wouldn't buy it... The price absolutely matters and Bitcoin blocksapce is expensive as shit.
