Two considerations:

1) Since most of the real estate values are capital gains,
there might be a net financial advantage when and if real estate was sold
after the trusts had been disallowed, inasmuch as capital gains income tax rates
are (much) higher than (Massachusetts) estate tax rates. The disallowance
of the Trusts would set a much higher basis from which capital gains would
be calculateds, and capital gains taxes would be corresondingly much lower.

2) The good faith existence of any real estate trust will be corroborated 
by the manner in which its assets are sold. When real estate in trust is sold, 
it would arguably be improper for a deed to be issued until all shareholders had 
voluntarily sold their shares of beneficial interest either to the Trustee as middleman 
or preferably to a third party middleman to whom the Trustee would simultaneously
convey the legal interest. Then the middleman, holding both the legal interest
and all beneficial interests, would be in a position to issue a deed "in fee simple" 
with or without, but preferably without warranties.
