It's worth emphasizing that this decision did not legitimize same-sex marriage or anything else. It only decriminalized same-sex relationships to the same extent as hetero relationships, and these relationship MUST have ALL the following characteristics:
(1) Between (among) full adults,
(2) Entirely voluntary,
(3) Entirely in private,
(4) Non-monetary.
There are still laws on the books that criminalize any relationship - hetero or homo - that lack any one of those characteristics.
How about the intrusion on the State of Texas - from the federal government? How about if the State of Texas - or some other State - has a law stating that the age of consent for sexual relations is 16, and the 9 justices say, No, it has to be 12, like in the Netherlands? Do you call that freedom, or government intrusion?
