laws exist to cover for the majority of use cases, not individual, well reasoned exceptions. start with hammurabi and read on, the worl of bureaucracy has a lot more background and sense than you imagine.

Assuming your friend lives in a democracy, and assuming your friend wants you randomly visiting, then if as you say your friend didn't vote on the immigration laws, tell them to be more active.

Have them write to their politi-critters. Get the law revisited. If enough of your friend's friends also agitate and your neighbors generally agree or at least don't oppose, the law will be revised -- problem solved.

If, on the other hand your friend is in the minority, and you being able to visit without immigration permition is still that important to them, they are welcome to emigrate to somewhere visits without visas are open to you.

it comes down to trust. if i were to guess you lock the door to your house. why would you do something which limits the movement of people who want to be in your house. but at the same time you do not have problem giving access to your house to specific people (people you trust). it is same with countries just more complicated as now you are dealing with bunch of people rather than an individual.

visa free travel exists before countries agreed to trust each other for whatever the reason may be (economic/social/etc.). other countries can workout ways for travel but they do not think of it as a priority.

And who are you to decide what's good or not?
