None of those things would change if you became stateless. In fact, since renouncing costs something like 1800 pounds right now, some might get worse. Frankly, I don't think it would ever get to that point because the embassy could easily ignore the law and not allow the paperwork to be filed (you can Google around to find this does happen) but there is nothing good about being stateless:

It's taking the UK up to three years to decide these applications and less than 10% are being granted. While the decision is being made you will not have permission to work or anything else you don't have already.
Furthermore, unlike genuine refugee status, becoming stateless by choice is not even necessarily something that would stop the UK from deporting you. This is what the guidance notes say:

4.6.6 Voluntary renunciation of nationality
Voluntary renunciation occurs when an individual gives up his or her nationality
through choice, usually by oral or written declaration. The subsequent withdrawal of
nationality by the State may be automatic or at the discretion of the authorities.
Although many States have safeguards in their nationality laws to prevent this from
leading to statelessness, it continues to occur.
Sometimes individuals have to renounce their nationality in order to naturalise in
another State and may then remain stateless if they do not acquire the second
nationality. In other cases individuals voluntarily renounce their nationality because
they do not wish to be nationals of a particular State or in the belief that this will lead
to the grant of a protection status in another country. Those who have renounced
their nationality voluntarily may be able to reacquire such nationality, unlike other
stateless persons.
The question of an individual’s free choice is not relevant when determining eligibility
for recognition as stateless under Article 1(1) of the 1954 Convention, even if it
appears that the applicant may have been motivated by the prospect of securing
leave to remain as a stateless person. The applicant must nevertheless be asked the
reason for renunciation and the possibility of re-acquiring that nationality must be
examined very carefully in such cases. Loss of nationality and consequential
statelessness will not necessarily prevent re-admission to the country concerned.
Where there is evidence to suggest that someone has deliberately renounced
nationality in an attempt to benefit from stateless provisions, and there remains an
option for them to approach the relevant State to reacquire their former nationality,
the stateless application should be refused.
Whether reacquiring your US citizenship would still be an option is not an easy question for myself (a former US immigration attorney) to answer and would probably require a court case, taking years and thousands of pounds/dollars, to decide; as I'm not a UK solicitor or barrister I have no idea how you would go about proving this either way. The fact that Joel Slater got his back through more or less asking nicely does not bode well, however. If you cannot afford the fees for the normal immigration process you definitely cannot afford to gamble on this.
This is not nearly everything that could go wrong, but hopefully enough to convince you that this is an extremely terrible idea.
