I do not think this is an over-restriction. These types of restriction are needed to keep the overall benefits in mind, instead of doctors being influenced by gift. The gift can easily be seen as bribes and this is a very unethical topic especially in the medical field. “Gifts” are a great technique to do business with, but fields like healthcare and other heavily regulated fields should have great restrictions on how businesses influence their clients. The idea and practicality of something should influence a decision, not the value of the gift from a company. This keeps the people potentially affected by the business transaction protected.
