You're right.

PayPal, Google and the Tor Project will probably just stop working
in Kazakstan, and either they decide to follow the duly enacted
and valid laws of that country, or they will not be doing business

For Kazakstan they *might* be able to shrug, although the track-record
indicates that the first two tend to follow local laws.

I have no idea what the Tor project will do, but fortunately the
human rights activists I know about has a fallback.

But have you followed the political discourse in UK recently ?

Will PayPal, Google and the Tor Project be able to shrug it off
when the UK government makes a similar move ?

Dude, it's not high cost.  Kazakstan probably didn't even pay a
million dollars for their kit.

That response is a little bit ironic, coming from one of the loudest
"TLS everywhere" advocates...
