Bush meat is a rather more likely source. And the virus didn't "come from a cave".
The ancestral strain of the virus does infest bats that live in caves, but Covid-19 can infect humans, which the ancestral strain can't, and we haven't got a clue about the recent ancestors in which the ability to infect humans appeared, or which animals they'd been infecting at the time.
Pangolins have cropped up as a possible host, and they were sold as food at the Wuhan wet market

Anything is possible, but it's not a useful speculation.
Not so much a weakness as a necessary capacity. Cells have to be able to synthesise their own strings of nucleotides to be able to reproduce themselves, and successful viruses can exploit this capability.

What makes you think that - apart from a congenital weakness for
fatuous conspiracy theories?
There are numerous reports that they were cooperating with US
researchers on the SARS coronavirus in bats. That was discussed in
a thread here somewhere. The Chinese asked for more assistance and
we had embassy scientists inspect their facility. They recommended
we give them the assistance and we declined to act.
Whether or not this lab was the source of the pandemic is not yet
known, but it's not looking so improbable.
Only to a rabid conspiracy theory nut.
If there's one thing that research institutions do well, it is
stopping the different viruses they are studying from leaking from
one lab to next one.
If they can't manage that they won't be doing research that will be
taken seriously. Imagining that a virus could leak out into the
outside world takes a Flyguy level of mental incompetence.
Stuff leaks out of biolabs all the time. Usually, no harm comes of it -
sometimes people die.

It is not at all unrealistic to suppose that the virus spread after an
accidental leak from this lab. (Equally, there is - AFAIK - no direct
evidence that this is what happened.)
Intentional leaks, bioweapon research, etc., are the stuff of conspiracy
theorist fantasies. But accidents happen despite the best of
intentions, the best of routines, the best of staff, the best of equipment.
The best argument for the SARS-CoV-2 being from a Chinese lab is that the argument for it coming from the "live" fish market is poor.
It was primarily a live fish market, but it did sell various sort of wild animals for food as well.

Viruses are very strange pathogens. They are the ultimate expression that the purpose of life is to replicate nucleic acids. The corporeal expression of the nucleic acids are just a means to an end... propagating the information contained in them. In the case of the virus, there is never really a viral organism, just an incredibly simple carrier of the nucleotides.
Viruses are really just nucleic acid accidents that happen to be able to exploit weaknesses in their hosts.
Not so much a weakness as a necessary capacity. Cells have to be able to synthesise their own strings of nucleotides to be able to reproduce themselves, and successful viruses can exploit this capability.
