This is like if I portion out my income and say "money from gig A goes to bills, money from gig B goes to savings"
At the end of the day if bills get bigger I can always pull money from gig B because I own the income stream. Just because I can currently accurately apply these arbitrary labels doesn't mean those labels aren't arbitrary, and it doesn't dictate what I will do with that money in the future.
It would be a bad idea for the owner of the income streams to actually make spending decisions based on the size of each income stream. You should always choose the expenditure with the highest expected value.
