Infinitive ' habere ' usage in this sentence

Question

How to understand a meaning of the infinitive 'habere' here, is it here as a subject (The Infinitive as a Subject, Gildersleeve & Lodge, page 275)?

Nam cum posse existere potentia sit, sequitur quo plus realitatis alicujus rei naturæ competit eo plus virium a se habere ut existat adeoque Ens absolute infinitum sive Deum infinitam absolute potentiam existendi a se habere, qui propterea absolute existit. (Spinoza, Ethics)<

For, as the potentiality of existence is a power, it follows that, in proportion as reality increases in the nature of a thing, so also will it increase its strength for existence. Therefore a being absolutely infinite, such as God, has from himself an absolutely infinite power of existence, and hence he does absolutely exist. (R.H.M.Elwes)

eo plus virium a se habere ut existat <

..., more strength from itself (it would) possess in order to exist,...

Answer 1

Accusativum cum infinitivo triggered by sequitur, though the accusative has been ellipsed: 'it follows that it has...'

This use falls under definition 7 of sequor in the Oxford Latin Dictionary:

7 To follow from (a premiss), follow logically.
