What you're complaining about is overreach by the IRS in relation to foreign assets held by US citizens (ie FATCA) and the reporting requirements (eg Form 7938 and FBAR). It's worth noting that real estate is carved out as an exception for reporting purposes somehow, even though it's a common vehicle for money laundering.
That has literally nothing to do the Double Irish Dutch sandwich, which has historically been used by US companies (particularly Big Tech companies) to avoid taxes by moving their IP to a foreign subsidiary and then paying "royalties" to avoid paying US taxes.
