i been reading that border guards can demand access to laptop and look youre computer , email , facebook messages ect
Assuming you`re talking about the US specifically, that was the situation for
the past few years.
Not so much anymore. For a while there, DHS and successive administrations were of the view that it could do anything it wanted with regard to confiscation of anybody`s laptop at the border for off-site inspection, and they were claiming that the mere fact of password-protection was evidence of wrongdoing which would justify them in seizing the computer.
Now, they have to have "reasonable suspicion" (which is a lower hurdle than probable cause, but still more than "I felt like searching") in order to seize your device(s).

anyone else finds this a bit intrusive?
It`s super intrusive. I can understand the reasoning behind it, but I don`t agree with it and I don`t think it`s especially effective. It`s unfortunate that this particular ruling came after an investigation where they actually DID find pictures of the guy abusing children. My guess is that most people just don`t challenge it far enough when they don`t have anything to lose. I mean, if you have your laptop taken away, examined, and then maybe taken offsite and returned to you a few months later - what are you going to do about it? Be pissed off for a while but little else? Or challenge it to the highest court in the land? Most people go for the former, because it`s mainly the principle and most people don`t have the cash to fight a legal battle over such a principle.
If for some reason they do have reasonable suspicion, they can still take your laptop, and a court order can still compel you to reveal your password. Whether you can do that, and whether you have adequate encryption to provide some kind of plausible deniability in such a situation, is a whole different story.
Anyway, based on this ruling the ability to do this has been diminished though not eliminated. And in the UK, you can be sent to jail *just*
for refusing to reveal your password, depending on what offences you are being charged with. See also

I`m being lazy and not providing links to the cases themselves, but these articles give you the general gist.
Bottom line is that there`s a bit of a storm brewing regarding cryptography, and the state actors are very interested in limiting its usefulness.
