The problem is that people come to cryptocurrency not for the tech, or for investment diversification, but to make easy and quick money.
There is no easy quick money in this world. Even for BTC holders since 5+ years ago it was hard. Even for me, holding for 2 years, it was hard.
Then those easy quick money newbies come and buy shitcoins, look for giveaways, airdrops, whatever, which are mostly scams.
I agree with you, and just like you have said this mindset of trying to get or make some quick money this makes the scammers job easy because we like shiny things and fall prey these giveaways,airdrops, discounted giftcards etc.
We urgently need a change of mindset if we want to put an end to all this.
