We can't add more inventory space.


Unless you pay an additional $5.[...]

Truthfully, this is more about perception than anything else. They said the regular synced inventory is what can't be expanded further (beyond what they did with SB), and the whole reason for developing the saddlebag and glamour dresser was to work around those limits. So now that they worked around the limits by developing these other methods, they can expand it further using this these various kinds of "side-storage" (which isn't limited like regular inventory, though may have its own limits too).

I'm sure they'd probably argue that they already more-than-doubled people's storage space since the launch of SB, and that they've always sold extra storage capacity as an add-on. Objectively they're not wrong... but, as your quote points out, it won't really change people's sour perception that they're selling part of the solution to the problem.
