I don't remember this happening as you describe it.
Do you mean TCJA (tax cuts and jobs act)?
That one had some positives as well as negatives.
Negative was that you could basically deduct only the standard deduction and you can put in only $10k in RE tax.
charity for middle class became mostly meaningless since you still just get a standard deduction.
Another negative-you could not recharacterize the Roth conversion (from IRA) back to IRA-that one hurt as it was very useful if a stock price declined.
Positive-20% deduction on a pass through income for businesses, immediate expensing in section 179.
All and all-for me, personally, taxes did not change much.
Additionally, presidents do not pass laws, that's the job of the legislative branch. Though it would be interesting to know which lobbyist group wrote it.
The text in question appears to be section 13303 (3303 in the original).
SEC. 13303. LIKE-KIND EXCHANGES OF REAL PROPERTY.
(a) In General.--Section 1031(a)(1) is amended by striking
``property'' each place it appears and inserting ``real property''.
And a bunch of other stuff I won't clutter this thread with. It's interesting as it's almost as if it was written to target cryptos without looking like it was targeting cryptos.
