I don't know if the Long Tasks rules necessarily assumes you're not taking bathroom breaks, just that you're extending beyond the usual 8-hour work period which tends to include them.

You cannot injure yourself just by refusing to pee.

Sphincter failing first seems like it would be an issue if you had fecal matter in there, but wouldn't necessarily apply if someone were only consuming liquids (ie juice fast, etc). Obviously two explanding interior balloons are going to compete with each other for space, but there's going to be a space maximum regardless of how it is reached, and as you approach that maximum both ballons are going to take more willpower to avoid emptying.

Could definitely be a cultural thing (hey maybe there's a reason it's called Quick and DIRTY enchanting?) although if someone had "Phobia - wetting oneself" it might pressure them to either hold it in or abandon the ritual casting as they have competing motivations of "avoid phobia" vs "finish the ceremony" vs "not take HP damage"

The necessary powerstone is about 3490 carat big, at least dozens of times bigger than anything in the whole GURPS history, in Magig Items ? is somewhere a stone bigger than 100 carat. It is worth several kingdoms. The whole case is most likely a thought experiment.

M156's Black Magic rules allows you to reduce costs by triple your Occultism Thaumatology, so I guess that could get us part of the way there. That's more of an easy way to get over the hump of creating your first powerstones though.

We could just assume that mages doing this, if they don't have 3500 FP, might have an ER of 3500.

You might not have a full-time ER of 3500, maybe it's smaller but you can temporarily get access to higher ER deposits via Extra Effort.
