Back wheel is costlier to replace (due to gearing, assuming it’s not a fixie/single speed), so I prioritize locking the back wheel if I can only do one.
If you have quick-release axles and don’t want to worry about having your wheels stolen, most bike shops have security axles, which have a special key to loosen the axle. I’ve used them in the past for some extra peace of mind. Just dont lose the key(s)!
Some people have zero respect for their own lives, and by extension, any living thing. Money insidiously affects all, whether you’re a have or a have not.
We must try our best to nurture and understand our world instead of “conquering” it.
