His comment that his scraper dulled quickly tells us that the edge did not hold. Unless someone is prepared to hone their scrapers frequently in the middle of a job, why not go with other proven methods that are more efficient? Based on his video, my scrapers last at least 10 times longer than his. No exaggeration.
Gouging a stone is not uncommon if a woodworker presses a scraper down with too much force, while staying at the same spot on the stone.

Like I have said, I have tried honing. What I found was that with a clean fine file, there was really not enough difference and it was simply faster to skip the honing. I have scraped an inch or two of lumber and card scrapers dull fast either way they are sharpened.

A short length of a HSS planer blade makes a good scraper that lasts a long time if you make a holder for it..You can also use a HSS parting tool...Dress the edge on a carborundum hone and turn a small burr with a polished carbide rod...I use a carbide rod that TonyZ so generously sent me. For a rough burr, it can be created on a 120grit grinding wheel...no turning necessary, as Paul Hamler points out in his scraper video.

Dang Jack, I still have a bunch of old planer blades collecting dust. Made a few marking knifes out of them, but never thought about scrapers. Now just need to figure out a holder of some sort. I have used a wood lathe scraper to scrape the bed of a wooden plane. Really worked well in that application and the heft and length really helped in controlling it.
One problem I bet some folks have with sharpening card scrapers is that we try to get the most life out of a file and they get pretty beat up, grungy, and full of metal from previous jobs. Also, files can be flexed easily. Placing the file on a flat block of wood and working the scraper on it, will keep the file flat.
