It is an interesting theory; but I don't think it holds up very well on close inspection.
For one thing, human 'trust' is mostly about raw familiarity. If trust were linked to actual trustworthiness, politics would be completely different and "any publicity is good publicity" wouldn't be a proverb. Motivated untrustworthy people generally have great success getting people to trust them, drinking involved or otherwise.
In addition, trust even being an assessable characteristic is debatable, people's reliability is very dependent on context and circumstance. Nobody is trustworthy in a divorce court, for example.
"causes people to get along more freely and easily" makes a lot of sense, but the utility drunken parties for assessing trustworthiness seems weak.
