If the government wants a tax to be paid they need to make it simple and unconditional. If there are loopholes or ways to legally avoid it, they will be discovered and people will take advantage of them.
One thing - and this may not be your intent - that often happens is that people will disingenuously use "nobody should do more than they have to" as sleight of hand to point in the direction of "oh it's the law that's bad" with no intent of actually encouraging fixing the tax code.
Another thing is that there's often a big difference between the letter and spirit of a law, since the laws are made by imperfect humans and other humans have FAR more cumulative people-hours available after the law is passed to find holes. There is likely no such thing as a "simple and unconditional" tax law that can't be worked around in ways its authors did not intend. And here this may seem circular - "then the government should patch the hole" - but of course that would be great and yet it is something the government is rarely incentivized to do when people with money give them that money to influence them to not want to.
