"Avoidance is what we all do, perfectly legally, avoiding paying more tax than we need to. If you do not ensure you are not paying unnecessary tax then more fool you"
Evasion is the illegal bit and it is not just the rich and wealthy, undeclared cash jobs, undeclared tips. Undeclared rent income also is not just for the wealthy or well off.
No one can disagree with both of your statements above and no one can disagree that evasion needs stamping out.
I can even agree that no one should pay more tax than they need to and that the tax system should be made far simpler.
However, you are happy to go along with, use and even profit, out of the 'avoidance route'
No one can say that is illegal but I am perfectly entitled to dislike it and want this and any other government, to plug these loopholes.
You are also correct to say that services such as you give are in place for everyone.
However, it is not true that everyone can take advantage of your services. Many simply don't know about them, cannot afford them or do not have it within them to seek you out and some even see paying their tax as their duty.
Also there is a vast difference in the reasons why a wealthy person wants to avoid Tax and a pensioner trying to survive, needs to avoid Tax.
Evasion is the same, it is all wrong but the reasons are far ranging.
You cannot compare the evasion by a single, already wealthy person, amounting to £millions against a waitress struggling to survive by keeping her tips.
