Wishful thinking doesn't prove anything.
Either way, the disciples left their former lives behind to spread the Gospel and a few already had itinerant jobs to begin with: as many were fishermen. Paul worked as a tentmaker, etc...
But they didn't leave their wives behind.
1 Corinthians 9:5 Do we not have the right to take along a believing wife, as do the other apostles and the brothers of the Lord and Cephas?
Wives can and do work very successfully in partnership with their husbands in spreading the gospel and ministering to people.
There's no way a man of any integrity would leave a wife behind and abandon her to fend for herself.
Nobody said anything about a man abandoning his wife to fend for herself.
Soldiers, like many (but not all) missionaries, left their wives and families for years at a time, and soldiering would have been a metaphor close at hand and quite well understood as being based on the ethic of sacrifice.
But they didn't abandon wives and children to "fend for themselves". They also had a splendid ethic of supportive kinship and an extensive, sharing community.
Matthew 19:29 KJV
And every one that hath forsaken houses, or brethren, or sisters, or father, or mother, or wife, or children, or lands, for my name's sake, shall receive an hundredfold, and shall inherit everlasting life. .
