You can short it elsewhere.

Schwab won't let you, because even if you're 95% right, you'll still probably lose 95% of your money...

It's quite difficult to be 100% right...

You and your broker have to be pretty damn brazen to iron grip a highly liquid stock all the ways down to -95%.
Shorts can go down to -1000% and beyond.
Yes, but you have to hold through that, and your broker also needs to let you hold through it.

The risk of a stock like spaceX gapping up 10x in an instant is virtually zero.

Not true: Depending on product and regulatory regime, for distinct trader/customer groups there may be distinct rules.

And if you are buying an instrument where you can lose more than you invested, the approach maybe wrong? :-)

This is precisely why shorting can lose more than you "invest", because you're not buying an instrument, you're selling it with the intent (or promise, depending on what kind of instrument it is) to buy it back later, hopefully at a lower price.

The risk is unbounded.

There are, as said, depending on juristic regime, products which do not let you lose more than you invested.

On top of this comes national regulation: E.g. in some EU countries, retail traders are exempt from s.c. "margin calls" and the broker is required by regulation to "just close and not ask for more"
