Kazakhstan is not China, it didn't have that much excess cheap power as the China of 2019, it doesn't have overall that much electricity generation and most importantly it lacks the advantage of having the manufacturer in the same country speaking the same language and not requiring all the papers for imports and setting up a business.
If Kazakhstan has 10% of the hashrate and everything will be shut down at the same time it will currently mean little there are bigger problems.
We have still empty blocks getting mined, we've only had one period longer than 24 hours where a 1sat/b tx wouldn't get included over the last month so it will not affect the fees that much, over a longer period just a few of the companies operating in the US have more or at least 50Exa of mining gear on order till Q2 not including XP shipments, so that's double the hashrate of Kazakhstan.
The only serious impact it will have is that it will clearly make the US the next China, you can expect them to reach even 75% if this shit goes on.
Higher electricity prices all over the world will put more pressure on all miners than some government going after small miners.
According to the country’s Transport Police Department, which carried out the search, the officers found 130 crypto mining units as well as hard drives and spare parts.
Also, nobody is saying all of these are Bitcoin mining Asics, it can be anything, even Chia!
