There's a big difference between seceding half your contiguous realm to gain a second recruiting center on the other end of it—or moving the capital so that your recruiting center is there—and carving out a forward base in enemy territory, a long way from home.
Well yeah, if anything it's even worse. There are mechanics that make it virtually impossible to wage war at great distances in BM. Tom has repeatedly said that this has been done
on purpose, and various suggestions to make it easier to wage war on the other side of the island (cash bonds in allied cities, recruit anywhere in your realm) have been shot down more than once based on this exact justification. Carving out a forward base a long way from home to
make it possible to wage war at a long distance seems exactly like the sort of meta-game shenanigan that the strategic capital move rule is aimed at preventing in the first place.
