Also what would be the point of crystalizing himself? Nobody else could become a titan so there's no danger of being eaten and losing the founder. He could just let the curse kill him and he'd be the last titan. While I too agree with your first statement. Like, if the Founding Titan could just do that, why didn't the Karl or any of descendants try?

But onto your second point, even if the ability to transform into titans was removed, the Eldians are still connected by paths, unless its powers could somehow completely make somebody not Eldian, in which the above statement is even more prevalent. So if Eren were to die, the powers will still end up in other hosts randomly. So assuming crystalizing acts like an indefinite stasis, that would be one way to keep it out of people's hands. Maybe unless Eren takes that power of paths. I think Karl didn't try that because he values his people's lives and wanted to create a safe paradise of course his way of doing things was messed up but I think he thought that nobody would wanted to be in Crystal prison forever.
