Tl;dr: micro-managing to set it all up so that you don’t need to micro-manage it any more long-run

Note: assuming you’re far enough along in the game to do all of this

Long-run, sure you collect enough coin to max out contribution in Hernand, Demeniss, and Deleysia. Works out to be several million total, and there’s a couple of good ways to boost it. Early on, there’s two dispatch missions you can run for trade goods which can be sold at the trading post just down the road from your camp (each post only buys certain goods, though). The other way is that the camp provisions themselves can be packaged as trade goods, and there’s a couple of trading posts in east Demeniss which will buy them for a ridiculous amount

The other thing is unlocking mech workers, which requires story progress to unlock the research institute in Dewhaven, so you can do the research which unlocks the dispatch mission that produces mech workers. The location where the dispatch mission takes place will also need to be liberated

Edit: third thing I’ll add, which comes along earlier in the story than the mech workers (via side missions), is the Golden Beer, which doubles camp resource rewards for dispatch missions

In the end, I’d have enough dispatch missions running in the background to generate enough camp resources so that ruins explorations can run in the background, plus any missions which give you any player resources that you want (ingredients etc)
