Whihch is exactly what the vast majority of father's rights groups want and push for. They also push for laws limiting one parent from moving to another area thereby limiting the amount of time the other parent has the child.

Could you please post a link to these Father's Rights groups who you say support default JPC judgements, referred to in the legal jargon as Rebuttal Presumption of Joint Physical Custody (RPJPC)?

I'm haven't seen that Father's Rights groups support RPJPC, nor do mainstream feminists groups. Neither one wants that because they want the wiggle room to have child custody be a bargaining chip in gender politics.

If we HAD true RPJPC, a parent would have to specifically petition a court to NOT be required to take his/her 50% share of physical custody and to make other arrangements, including moving geographically from the child(ren). Don't get me wrong, I think people should be able to make alternative arrangements from the default position. That would be fine, but then we'd have a TRUE statistical picture of who and why people don't want 50% custody.
