Biggest "issue" is that in a 2-3 years the whole new generation of people will enter crypto and for them all that has happened with FTX and other platforms will be a distant memory. And since people often don't learn from their own mistakes let alone others, they are bound to do them.
That's why the exact same thing keeps happening every single year (larger exchanges more like every 2-3 years) almost since the inception of Bitcoin.
After the hack / exit scam / insolvency, there is a big push towards self-sovereignty, only for people to fall back to the next 'we are not like the others' centralized exchange.
Some people hold their crypto assets on exchanges, it is very dangerous, previously many exchanges have been hacked.
I advise You should keep your crypto assets in your personal wallet because the exchange is not safe.
