Massive social engineering mean the IRS would need every financial and legal transaction you've ever participated in. Which they clearly do not.
For example, we don't have a simple tax system based on a percentage of salary. The amount they want as a tax depends on your marital status, how many kids, how much your spouse earns, and if you itemize deductions it gets even worse WRT every medical provider's bill you've ever paid and weird details of interest payments on mortgage loans.
Honestly the error rate of trying to gather all that big brother data is almost certain to be higher than the fraud rate of people in general.
Also people push agendas, so if you want to spread the idea that fraud is rampant, if I get free coffee at church and starbucks has proven 52 coffees per year is about five hundred bucks, not declaring that coffee as income is fraud; with paper money and barter the IRS can't get all "weird" about little details, but with digital currency if you buy a donut, there will be a reckoning simply because its possible.
