I was not really going for badass as much as countering an objectively incorrect statement.Seems we have a real badass here, don't mind us and keep going ur investments.
I actually agree with the sentiment (don't invest what you can't afford to completely and utterly lose, same thing I say for gambling as well) but the markets were not in free fall during lockdown, that fall had already happened prior to it.
I would not say it is gambling either -- there might be skill in gambling but ultimately it is still chance based. If you are not chasing the crazy returns you can pick good companies doing good work (or at least monopolies), maybe have a go at shorting bad companies, and if you keep half an eye on things then you can also get out when things start looking like they are taking a turn for the worse (collapses are rarely instant and might take several days), and even if you can't be bothered with all that then index funds are generally pretty solid in most of the free world over the course of years/decades.
