First because as I said its a decision for society, just as it isn't exclusively my decision to pay more tax, it shouldn't be exclusively Joe Bloggs decision to pay less tax. At the extreme you could make all taxes voluntary, I don't think that would work because too many people wouldn't pay enough,(or indeed anything), then you'd get a second wave watching those not pay anything and stop contributing themselves.

Second, its a bit abstract, there isn't 'a cause', it's taxes, I don't like paying taxes, just like I don't like going to the dentist, but it needs to be done so I do it. The dentist says come back in 6 months, so I come back in 6 months. I trust that people who know about dentistry than I have reached the decision on 6 months for good reasons, and if more data comes to light, I would support them updating those recommendations, but I wouldn't voluntarily visit every 3 months, without that recommendation
