I don't know a way of changing that default, but did you know you can click and
drag to move a worksheet and ctrl-click and drag to copy it?

If you tile your windows nicely, it makes it easy to copy/move between
workbooks, too.

When you right click the sheet tab and select "Copy or Move...", a dialog
opens with a check box for "Copy Sheet"
Is it possible to have this ticked by default - I find I do far more
copying of sheets than I ever do moving.
