A society in which "the average car-buyer" has a tiny portable steel-melting laser is a society where I'm wearing welding goggles every time I leave the house. And I'm not sure how you even lock a bike or a door or a safe any more.

There are already so many ways to defeat locks, that locks are just there to keep honest people honest and to slow down criminals. The laser in the article took 30 seconds to cut a a tiny disc out of a sheet of steel 100 micrometers thick. That isn’t going to change things on the theft front. There are much more effective methods available today.

The same can be said of BB guns that can put out eyes, lock picks that can open locked doors, and bolt cutters than can break chains. More powerful tools are a good thing.
The article rightly points out the industrial impact of more powerful and compact lasers but I cannot wait for those PCSELs to reach the small workshop market. Having a cheap laser able to cut metal at home / small shops would be so useful (And sneakily dangerous as lasers are).
Can you expand on why you think this would be so great for home workshops? How do you envision using the laser? Handheld, mounted, or on a CNC?
At the moment, there are expensive-but-affordable home CNC laser cutters, typically for a small number of thousand EUR/USD. The more powerful ones can do a very neat job cutting (up to a few mm of) plywood. There are also CNC plasma cutters, which do a good but slightly rough job of cutting sheet metal, and are relatuvely large and complex beasts. I guess a highly-powerful laser, of the type envisioned, would offer the best of all worlds: relatively neat and quick cutting of all materials on the same compact machine.
They might also replace handheld plasma cutters (and welders?) too.

A dutch women told me once a story, where she but a used bike in Amsterdam and the heroin addict who sold it to her, threaten her to steal it again, if she does not use a heavy lock.

This is a terrifying prospect indeed, especially being located in the Netherlands, plenty bikes are getting stolen left and right already. But I guess this is inevitable, so we'll just have to devise better solutions than the simple locks which in their working principles have not changed in the past 100+ years. Great market opportunity around the corner I suppose.

Everyone can already afford a stick welder. We don't need goggles when we leave the house.

CNC would be an obvious implementation. At the moment, there are expensive-but-affordable home CNC laser cutters, typically for a small number of thousand EUR/USD.

I don't see how a laser would be an improvement on any of those, unless the goal is to CNC with extremely tight tolerances, but even then... it seems unlikely that you'll be CNCing blocks of metal, more likely just 2D cuts from sheets of metal, which is pretty limiting.
It would certainly be fun for some stuff, but I think the danger level of a super high power laser detracts from the fun.
More powerful cutting lasers would definitely be great for industrial use cases.
