Highly unlikely considering that Hamilton's mom was black.
The "US was created by and for white-male landowners" is little more than 20th century communist propaganda designed to portray the US as always having been an exploitive system. There was never any Federal constitutional requirement to own land in order to vote, and if it was limited to pure whites only then Hamilton himself would've been unable to vote due to his mixed heritage.
(Of course, this fact actually tends to reinforce your overall argument, even if it disproves your one concession to the previous bogus argument being presented).

"was the illegitimate child of James Hamilton, the younger son of a Scots laird, and Rachel Faucette, a woman of British and French Huguenot descent who had fled from her first husband. (Chernow's extensive research has uncovered nothing to substantiate claims that Hamilton, by way of his mother, was partly black.)"
And I never said that there was any Federal law requiring a citizen to own land in order to vote. It was one of many ideas conceived during the first Constitutional Convention that was voted down. Hamilton thought it a good idea, but the majority of his contemporaries, including Jefferson and Madison, did not. He was outvoted.
