Because straight in approaches at an uncontrolled airport
disrupt the pattern that everyone is using.


No more so than entering on the downwind .



Perhaps if there
were no other traffic at the time, it would be perfectly fine
but when everyone is in line and doing their thing, someone
cutting in sucks.


A straight-in approach is not "cutting in". Too many pilots believe pattern
traffic has the right -of-way.



There is a fairly large municipal airport
nearby that accommodates jets and sometimes, we single engine
folk have to anticipate them, but it still disrupts things.


Right. It's far better to have the jet fly a full pattern and mix it up
with the single engine folks than to have the single engine folks extend
downwind to follow a jet on a straight in approach.
