It seems like the comment (from a former tax advisor) you are responding to is explaining that the high cost of gaming the system is cost effective for large companies, but not for individuals. In that respect, it "makes sense" that individuals cannot take advantage of these loopholes that companies use.
In contrast, you seem to be arguing a different point--that, to you, it "doesn't make sense" that the system is designed poorly.
I don't think so. I interpreted the comment the same way probably because the comment was replying to one disputing the morality of it, not the feasibility of it.
What would happen if we did away with the income tax, sales tax, estate tax, property tax, and all other taxes?
The government could simply finance itself by printing money / inflation. Let’s say the government total expenditures were 5% of GDP each year, then you would simply have 5% inflation.
This would solve all the problems we have with income inequality, worthless heirs of the wealthy hoarding riches, and of very complex and expensive IRS and CPA work.
Everyone would need to invest their money rather than stuff it under a mattress so they could keep it growing rather than allowing inflation to shrink it.
Why would anyone invest in your currency? Why would anyone hold your currency? What would your interest rates be? What would that do to businesses making decisions on borrowing for CapEx etc etc.
I've said that paying for CoronaVirus will probaby be done by inflation rather than taxes, but I'm not sure that as the only source of revenue it makes any sense
