Beginners are going to make mistakes. The consequences of losing seeds is lose crypto so if they lost the funds they'll learn from the big mistake. Patience & research is good but haste is bad so beginners who haven't used crypto should understand this.
Such stories happen quite often with beginners, especially often it happens for those beginners who do not understand the meaning of the seed phrase, and this is the basis of the basics, because with bitcoin you yourself become a bank and all responsibility for the safety of your coins lies only with you.
I always thought that it is good when this happens to beginners, because in the future it will become an invaluable lesson, and of course it is best if this happens with some altcoin that is not worth much and which will only get cheaper over time, and few will regret it in the future. But if we are talking about bitcoin, then over time it can only get worse, because it will become more expensive and the amount on the wallet to which there is no longer access will increase, such a torture for a mistake. Haste is bad, first you need to study everything thoroughly, understand the responsibility, and only then start buying bitcoin.
