Why don't people just buy a temperature scanner for family gatherings?

Why? That's because them scanners are made in China!

Because that doesn’t catch people who are asymptomatic but still contagious.

Most people do own a temperature scanner. They just do not think they need to use them.
Also the scanners are not reliable as a way of preventing the spread of COVID. Some people never develop a fever but are still infected and can spread it. You can also spread for a short time before the fever and after it breaks.
While it would probably reduce the spread, it would not prevent all spreading.
