Well of course they had a right, but they apparently renounced that right when they became Jesus' apostles.
"Then answered Peter and said unto him, Behold, we have forsaken all, and followed thee; what shall we have therefore? And Jesus said unto them, . . . 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."
I think your reading of that passage is off. Paul seems to be saying that he and Barnabas have a right to take along a wife, like the other apostles are actually doing.
I doubt the apostles would have actually abandoned their wives:
"In like manner also if any presbyter or deacon on pretence of piety has dismissed his wife, let him be excluded from communion; and if he persevere in this let him be deposed." (Canon XIII, Synod of Trullo)
